CXD3048R description of peak meter mode (see timing chart 1-5.) when the lsi is set to this mode, the maximum pcm data value is detected regardless of if it comes from the left or right channel. the 96-bit clock must be input to sqck to read out this data. when the 96-bit clock is input, 96 bits of data are output to sqso and the value is set in the lsi internal register again. in other words, the pcm maximum value register is not reset by the readout. to reset the pcm maximum value register to "0", set pct1 = pct2 = 0 or set the $ax command mute. the subcode-q absolute time is automatically controlled in this mode. in other words, after the maximum value is generated, the absolute time for crc to become ok is retained in the memory. normal operation is conducted for the relative time. the final bit (l/r flag) of the 96-bit data is normally "0". the pre-value hold and average value interpolation data are fixed to level (? ) for this mode. sens output switching this command is used to output the sqso pin signal from the sens pin. when soc2 = 0, sens output is performed as usual. when soc2 = 1, the sqso pin signal is output from the sens pin. at this time, the readout clock is input to the sclk pin. note) perform the soc2 switching when sqck = sclk = high. command bit soc2 = 0 soc2 = 1 processing the sens signal is output from the sens pin as usual. the sqso pin signal is output from the sens pin. command audio ctrl d3 0 data 3 d2 0 d1 0 d0 0 d3 0 data 4 d2 1 d1 0 d0 0 d3 0 data 5 d2 0 d1 0 d0 0 d3 0 data 6 d2 0 d1 0 d0 0 ? 55 ?

CXD3048R [2] subcode interface there are two methods for reading out a subcode externally. the 8-bit subcodes p to w can be read out from sbso by inputting exck. the subcode-q can be read out after checking crc of the 80 bits in the subcode frame. the subcode-q can be read out from the sqso pin by inputting 80 clock pulses to the sqck pin when scor comes correctly and crcf is high. 2-1. p to w subcode readout data can be read out by inputting exck immediately after wfck falls. (see timing chart 2-1.) 2-2. 80-bit subcode-q readout fig. 2-2 shows the peripheral block of the 80-bit subcode-q register. first, subcode-q, regenerated at one bit per frame, is input to the 80-bit serial/parallel register and the crc check circuit. 96-bit subcode-q is input, and if the crc is ok, it is output to sqso with crcf = 1. in addition, 80 bits are loaded into the parallel/serial register. when sqso goes high after scor is output, the cpu determines that new data (which passed the crc check) has been loaded. when the 80-bit data is loaded, the order of the msb and lsb is inverted within each byte. as a result, although the sequence of the bytes is the same, the bits within the bytes are now ordered lsb first. once the 80-bit data load is confirmed, sqck is input so that the data can be read. the sqck input is detected, and the retriggerable monostable multivibrator is reset while the input is low. the retriggerable monostable multivibrator has a time constant from 270 to 400s. when the duration when sqck is high is less than this time constant, the monostable multivibrator is kept reset; during this interval, the serial/parallel register is not loaded into the parallel/serial register. while the monostable multivibrator is being reset, data cannot be loaded in the peak detection parallel/serial register or the 80-bit parallel/serial register. in other words, while reading out with a clock cycle shorter than this time constant, these registers will not be rewritten by crcok and others. the previously mentioned peak detection register can be connected to the shift-in of the 80-bit parallel/serial register. for ring control 1, input and output are shorted during peak meter and level meter modes. for ring control 2, input and output are shorted during peak meter mode. this is because the register is reset with each readout in level meter mode, and to prevent readout destruction in peak meter mode. as a result, the 96-bit clock must be input in peak meter mode. the absolute time after peak is stored in the memory in peak meter mode as noted in "description of peak meter mode" on page 95. see timing chart 2-3. the clock is input from the sqck pin to perform these operations. the high and low intervals of the clock should be between 750ns and 120s. ? 102 ?

CXD3048R [3] description of modes this lsi has three basic operating modes using a combination of spindle control and the pll. the operations for each mode are described below. 3-1. clv-n mode this mode is compatible with the cxd2510q, and operation is the same as for conventional control. the pll capture range is 150khz. 3-2. clv-w mode this is the wide capture range mode. this mode allows the conventional pll to follow the rotational velocity of the disc. this rotational following control uses the built-in vco2. the spindle is the same clv servo as for the conventional series. operation using the built-in vco2 is described below. when starting to rotate the disc and/or speeding up to the lock range from the condition where the disc is stopped, cav-w mode should be used. specifically, first send $e665x to set cav-w mode and kick the disc, then send $e60cx to set clv-w mode if alock is high, which can be read out serially from the sqso pin. clv-w mode can be used while alock is high. the microcomputer monitors the serial data output, and must return the operation to the speed adjusting state (cav-w mode) when alock becomes low. the control flow according to the microcomputer software in clv-w mode is shown in fig. 3-2. in clv-w mode (normal), low power consumption is achieved by setting lpwr high. control was formerly performed by applying acceleration and deceleration pulses to the spindle motor. however, when lpwr is set high, deceleration pulses are not output, thereby achieving low power consumption mode. note) the capture range for this mode is theoretically up to the signal processing limit. 3-3. cav-w mode this is cav mode. in this mode, the external clock is fixed and it is possible to control the spindle to the desired rotational velocity. the rotational velocity is determined by the vp0 to vp7 setting values or the external pwm. when controlling the spindle with vp0 to vp7, setting cav-w mode with the $e665x command and controlling vp0 to vp7 with the $dx commands allows the rotational velocity to be varied from low speed to quadruple speed. (see "$dx commands".) when controlling the spindle with the external pwm, the pwmi pin is binary input which becomes kick during high intervals and brake during low intervals. the microcomputer can know the rotational velocity using the internal master clock frequency as the parameter. with xtal (xtai, xtao) (384fs) as the reference frequency, the result after measuring the high interval by the internal master clock is output in 10 bits (vp0 to vp9) from the new cpu interface. these measurement results are 31 when the disc is rotating at normal speed or 127 when it is rotating at quadruple speed. these values match those of the 256 ? n for control with vp0 to vp7. (see timing chart 2-5.) in cav-w mode, the spindle is set to the desired rotational velocity and the operation speed for the entire system follows this rotational velocity. therefore, the cycles for the fs system clock, pcm data and all other output signals from this lsi change according to the rotational velocity of the disc. note) the capture range for this mode is theoretically up to the signal processing limit. note) set flfc to "1" for this mode ? 109 ? CXD3048R 3-4. vco-c mode this is vco control mode. in this mode, the oscillation frequency of the internal master clock (vclk) can be controlled by setting $d commands vp0 to vp7 and vpctl0, 1. the vclk oscillation frequency can be expressed by the following equation. vclk = the vco1 oscillation frequency is determined by vclk. the vco1 frequency can be expressed by the following equation. when dspb = 0 vco1 = vclk when dspb = 1 vco1 = vclk 1 (256 ? n) 32 49 24 49 16 n: vp0 to vp7 setting value 1: vpctl0, 1 setting value ? 110 ?

CXD3048R [4] description of other functions 4-1. channel clock recovery by digital pll circuit the channel clock is necessary for demodulating the efm signal regenerated by the optical system. assuming t as the channel clock cycle, the efm signal is modulated in an integer multiple of t from 3t to 11t. in order to read the information in the efm signal, this integer value must be read correctly. as a result, t, that is the channel clock, is necessary. in an actual player, a pll is necessary to recover the channel clock because the fluctuation in the spindle rotation alters the width of the efm signal pulses. the block diagram of this pll is shown in fig. 4-1. the CXD3048R has a built-in three-stage pll. the first-stage pll is a wide-band pll. when using the internal vco2, an external lpf is necessary. the output of this first-stage pll is used as a reference for all clocks within the lsi. the second-stage pll generates the high-frequency clock needed by the third-stage digital pll. the third-stage pll is a digital pll that recovers the actual channel clock. the digital pll in clv-n mode has a secondary loop, and is controlled by the primary loop (phase) and the secondary loop (frequency). when flfc = 1, the secondary loop can be turned off. high frequency components such as 3t and 4t may contain deviations. in such cases, turning the secondary loop off yields better playability. however, in this case the capture range becomes 50khz. a new digital pll has been provided for clv-w mode to follow the rotational velocity of the disc in addition to the conventional secondary loop. ? 113 ?

CXD3048R 4-2. frame sync protection in normal-speed playback, a frame sync is recorded approximately every 136s (7.35khz). this signal is used as a reference to recognize the data within a frame. conversely, if the frame sync cannot be recognized, the data is processed as error data because the data cannot be recognized. as a result, recognizing the frame sync properly is extremely important for improving playability. in the CXD3048R, window protection and forward protection/backward protection have been adopted for frame sync protection. these functions achieve very powerful frame sync protection. there are two window widths; one for cases where a rotational disturbance affects the player and the other for cases where there is no rotational disturbance (wsel = 0/1). in addition, the forward protection counter is set to 12 ? , and the backward protection counter to 3 ? . concretely, when the frame sync is being played back normally and then cannot be detected due to scratches, etc., a maximum of 12 frames are inserted. if the frame sync cannot be detected for 13 frames or more, the window opens to resynchronize the frame sync. in addition, immediately after the window opens and the resynchronization is executed, if a proper frame sync cannot be detected within 3 frames, the window opens immediately. ? default values. these values can be set as desired by $c commands sfp3 to sfp0 and srp3 to srp0. 4-3. error correction in the cd format, one 8-bit data contains two error correction codes, c1 and c2. for c1 correction, the code is created with 28-byte information and 4-byte c1 parity. for c2 correction, the code is created with 24-byte information and 4-byte parity. both c1 and c2 are reed-solomon codes with a minimum distance of 5. the CXD3048R uses refined super strategy to achieve double correction for c1 and quadruple correction for c2. in addition, to prevent c2 miscorrection, a c1 pointer is attached to data after c1 correction according to the c1 error status, the playback status of the efm signal and the operating status of the player. the correction status can be monitored externally. see table 4-2. when the c2 pointer is high, the data in question was uncorrectable. either the pre-value was held or an average value interpolation was made for the data. mnt3 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 mnt2 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 mnt1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 mnt0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 description no c1 errors; c1 pointer reset one c1 error corrected; c1 pointer reset ? ? no c1 errors; c1 pointer set one c1 error corrected; c1 pointer set two c1 errors corrected; c1 pointer set c1 correction impossible; c1 pointer set no c2 errors; c2 pointer reset one c2 error corrected; c2 pointer reset two c2 errors corrected; c2 pointer reset three c2 errors corrected; c2 pointer reset four c2 errors corrected; c2 pointer reset ? c2 correction impossible; c1 pointer copy c2 correction impossible; c2 pointer set table 4-2. ? 115 ?

CXD3048R digital audio data input the input signal of the digital audio data is input through the dac input signal pins pcmdi, lrcki and bcki. the input format supports the 48-bit slot, msb first. mute function by setting the command bit dout_dmut to "1", all the audio data portions in the digital out output can be set to "0" without altering the channel status data. input/output synchronization circuit in normal operation, the dac automatically synchronizes with the input lrck. however, synchronization may not be achieved when the input data contains much jitter or during power-on, etc. in such cases, internal operation should be forcibly resynchronized by setting the $34a command dout wod to "1". forced synchronization is also required when the operating frequency is changed such as switching between clv and cav, etc. be sure to set dout wod to "0" and then to "1" for forced resynchronization. ? resynchronization clears the internal frame counter so that the count starts over from frame 0 after the resynchronization processing. in cases where automatic resynchronization processing is not desirable or the user wants to do it manually, set the $34a command winen to "0" to disable the resynchronization circuit. dout circuit clock system for the dout block, the master clock is set using the clock control command mcsl ($a) employed by the dac block. set mcsl to "1" for 768fs, and to "0" for 384fs. ? 123 ?

CXD3048R 4-6. servo auto sequence this function performs a series of controls, including auto focus and track jumps. when the auto sequence command is received from the cpu, auto focus, 1-track jump, 2n-track jump, fine search and m-track move are executed automatically. the servo block operates according to the built-in program during the auto sequence execution (when xbusy = low), so that commands from the cpu, that is $0, 1, 2 and 3 commands, are not accepted. ($4 to e commands are accepted.) when the auto sequencer is used, $9x command a.sec on-off is turned on. in addition, when using the auto sequence, turn the a.seq on-off of register 9 on. when clok goes from low to high while xbusy is low, xbusy does not become high for a maximum of 100s after that point. this is to prevent the transfer of erroneous data to the servo when xbusy changes from low to high by the monostable multivibrator, which is reset by clok being low (when xbusy is low). in addition, a max timer is built into this lsi as a countermeasure against abnormal operation due to external disturbances, etc. when the auto sequence command is sent from the cpu, this command assumes a $4xy format, in which x specifies the command and y sets the max timer value and timer range. if the executed auto sequence command does not terminate within the set timer value, the auto sequence is interrupted (like $40). see "[1] $4x commands" concerning the timer value and range. also, the max timer is invalidated by inputting $4x0. although this command is explained in the format of $4x in the following command descriptions, the timer value and timer range are actually sent together from the cpu. (a) auto focus ($47) focus search-up is performed, fok and fzc are checked, and the focus servo is turned on. if $47 is received from the cpu, the focus servo is turned on according to fig. 4-6. the auto focus starts with focus search-up, and note that the pickup should be lowered beforehand (focus search-down). in addition, blind e of register 5 is used to eliminate fzc chattering. concretely, the focus servo is turned on at the falling edge of fzc after fzc has been continuously high for a longer time than e. (b) track jump 1, 10 and 2n-track jumps are performed respectively. always use this when the focus, tracking, and sled servos are on. note that tracking gain-up and braking-on ($17) should be sent beforehand because they are not involved in this sequence. 1-track jump when $48 ($49 for rev) is received from the cpu, a fwd (rev) 1-track jump is performed in accordance with fig. 4-7. set blind a and brake b with register 5. 10-track jump when $4a ($4b for rev) is received from the cpu, a fwd (rev) 10-track jump is performed in accordance with fig. 4-8. the principal difference from the 1-track jump is to kick the sled. in addition, after kicking the actuator, when 5 tracks have been counted through cout, the brake is applied to the actuator. then, when the actuator speed is found to have slowed up enough (determined by the cout cycle becoming longer than the overflow c set with register 5), the tracking and sled servos are turned on. ? 125 ? CXD3048R 2n-track jump when $4c ($4d for rev) is received from the cpu, a fwd (rev) 2n-track jump is performed in accordance with fig. 4-9. the track jump count n is set with register 7. although n can be set to 2 16 tracks, note that the setting is actually limited by the actuator. cout is used for counting the number of jumps when n is less than 16, and mirr is used when n is 16 or more. although the 2n-track jump basically follows the same sequence as the 10-track jump, the one difference is that after the tracking servo is turned on, the sled continues to move only for "d", set with register 6. fine search when $44 ($45 for rev) is received from the cpu, a fwd (rev) fine search (n-track jump) is performed in accordance with fig. 4-10. the differences from a 2n-track jump are that a higher precision is achieved by controlling the traverse speed, and a longer distance jump can be performed by controlling the sled. the track jump count n is set with register 7. n can be set to 2 16 tracks. after kicking the actuator and sled, the traverse speed is controlled based on the overflow g. set kick d and f with register 6 and overflow g with register 5. also, sled speed control during traverse can be turned off by causing comp to fall. set the number of tracks during which comp falls with register b. after n tracks have been counted through cout, the brake is applied to the actuator and sled. (this is performed by turning on the tracking servo for the actuator, and by kicking the sled in the opposite direction during the time for kick d set with register 6.) then, the tracking and sled servos are turned on. set overflow g to the speed required to slow up just before the track jump terminates. (the speed should be such that it will come on-track when the tracking servo turns on at the termination of the track jump.) for example, set the target track count n ? for the traverse monitor counter which is set with register b, and comp will be monitored. when the falling edge of this comp is detected, overflow g can be set again. m-track move when $4e ($4f for rev) is received from the cpu, a fwd (rev) m-track move is performed in accordance with fig. 4-11. m can be set to 2 16 tracks. like the 2n-track jump, cout is used for counting the number of moves when m is less than 16, and mirr is used when m is 16 or more. the m-track move is executed by moving only the sled, and is therefore suited for moving across several thousand to several ten-thousand tracks. in addition, the track and sled servos are turned off after m tracks have been counted through cout or mirr unlike for the other jumps. transfer $25 from the microcomputer after the actuator has stabilized. ? 126 ?

CXD3048R 4-13-4. data linking in order to restart write after pcm data write to the dram has been interrupted due to sound skipping or other factors, continuity must be maintained between the data written last and the subsequent data to be written. conventional systems fix an aim at the data linking point, compare the preceding dram reference data with the data read from the disc, and then link the data when matching data is detected. however, when using music software where a fixed pattern is repeated, this system may link the data at an incorrect point. in addition, if pre-value hold or interpolation is performed at the point to be linked, data linking may not be possible at all. in order to eliminate these data linking errors, the CXD3048R generates a crystal accuracy scor (= grscor) synchronized to the pcm data to allow data linking along the time axis, thus greatly increasing the data linking accuracy. 4-13-5. data processing the CXD3048R accumulates pcm data from the cd-dsp block in an external buffer and then inputs the data to the dac block in sync with the internally generated fs system clock. at this time, the pcm data is loaded and read out at the same rate during normal playback, so data does not accumulate in the buffer ram. therefore, the loading rate must be increased. this is accomplished by setting the cd-dsp block to double- speed mode and doubling the loading rate until the ram is full. when the ram becomes full, data regeneration from the disc stops temporarily and the ram data is read out to create an empty area, at which point loading is restarted. these operations are then repeated to effectively use the entire area inside the ram. pcm data flow (example for 4m 1 mode) 4-13-6. system outline (when slxqok = 1 and slxwre = 1) the addresses for accessing the buffer ram data consist of a readout address (ra) and a write address (wa). the data to be written is not always correct, and the subcodes, etc. must be constantly checked to make sure the data is correct and there is no sound skipping. the CXD3048R checks subcode-q using the cpu, and defines the data by inputting a negative pulse to the xqok pin. this defined address (vwa) is loaded to the internal register and the data between vwa and ra is treated as valid data. wa advances at a speed twice that of ra, and ra is written by wa and read out sequentially in the order registered by vwa. when ra catches up to vwa, there is no more valid data and readout is prohibited (xemp = low). in addition, when wa catches up to ra, the buffer is full and write is prohibited (xwih = low). in this manner, write to the ram is interrupted when the ram becomes full and there is no write area or when sound skipping caused by scratches, external disturbances or other factors is detected. data continuity must be ensured in order to restart write. therefore, the CXD3048R returns to the last defined address, and the cpu accesses the defined address point it sent last (actually the data slightly before that point) and reads the subcode-q after the rising edge of scor. if the subcode-q matches the last defined address, xwre is made to fall and write is restarted when grscor comes high within 7ms. note 1) if xwre is made to fall when grscor is low, xwih goes low and the write prohibited state results. note 2) when grscor is low, vwa is not updated even if a negative pulse is input to xqok. therefore, set xqok high while grscor is low. wa vwa ra valid data cd-dsp shock-proof dac 4m dram ? 144 ? CXD3048R 4-13-7. data write (when slxqok = 1 and slxwre = 1) the pcm data input from the dsp is loaded according to the fs system clock inputs (bcki, wdci and lrci), and is written sequentially to the external dram according to wa when the xwre pin input goes low and internal write is enabled (xwih pin output = high). the written data must be checked by some means or other. the CXD3048R assumes data checking with subcode-q. in this case, the cpu reads subcode-q triggered by the scor signal output from the dsp to determine whether sound skipping occurred. if sound skipping is not detected, the cpu inputs a negative pulse to the xqok pin during the grscor high interval which comes within 7ms, and the data written to wa thus far is registered to vwa as data without sound skipping. scor subq grscor xqok no sound skipping = crc ok no sound skipping = crc ng wa vwa write prohibition is determined by the internal status or by an external command. when prohibited by the internal status, the xwih pin goes low, and this status is established when any one of the following conditions is met. 1. there is no empty area in the dram. xful = low 2. the dsp ram has overflowed. rof = high 3. xwre was made to fall when grscor is low. wrng = high 4. the dram write speed exceeds the set value. spover = high (when $a7 command xwih1 = 1) 5. access to dram in the shock-proof memory controller block failed. nowr = high (when $a7 command xwih2 = 1) 6. the number of c2po errors exceeds the set value. monc2po = high ($ae command wtc c2po = 1) 7. write is prohibited by the external input (a11 pin). (when $a7 command a11 sel = 1 and $ae command wtc c2po = 1) when the xwih pin goes low due to the above conditions, the cpu must set the xwre pin high and then the xwih pin high. after the cpu sends xqok, it must check whether xqok was registered as a defined address. this is because if the above conditions arise at the same time xqok is sent, xqok becomes invalid and the addresses defined by the cpu and the CXD3048R may not match. therefore, the xwih pin output is used as the xqok recognition signal (qrcvd) while xqok is low. when qrcvd is high, this indicates that xqok was correctly registered as a defined address (vwa was updated). when qrcvd is low, this indicates one of the following conditions. 1. write is prohibited due to the above conditions. 2. xwre is high. regarding condition 2, if xqok is sent while the xwre pin is high, wa, vwa and ra are all reset (when grscor is high). ? 145 ? CXD3048R 4-13-8. data readout (when slxqok = 1 and slxwre = 1) when data write starts, there is no valid data in the ram so the xemp pin is low. the xwre pin goes from high to low, and if there is no sound skipping or other problems with the crc check at the next scor, xqok is sent during the grscor high interval which comes within 7ms, and the defined address and valid data are registered. at this point, the xemp pin goes high for the first time and readout is enabled. data readout follows ra, and is performed in sync with the internally generated fs system clocks. the readout data and the fs system clocks are output from the data and the bck and lrck pins, respectively. ra is the address for reading out the written data that has been validated by vwa, and the area from vwa to ra is the amount of valid data (|vwa ? ra|). the upper 5 bits are output as am21 to am17. when ra catches up to vwa and there is no more valid data (|vwa ? ra| = 0), the xemp pin goes low and readout is prohibited. when this state occurs, the cpu must set the xrde pin high to prohibit readout. to restart readout, valid data must be registered as described above. the xemp pin is held low until valid data is registered. xwre xqok xemp xrde note) after the xwre pin goes from high to low, readout is enabled when valid data is registered by the first xqok. however, ensuring some difference between vwa and ra is recommended in consideration of crc ng, etc. see also "application notes" for the control of the shock-proof memory controller block. ? 146 ? CXD3048R 4-14. cpu to dram access function the CXD3048R can establish a special area in the dram. this allows a microcomputer to read and write optional 16-bit data to a portion of the dram area. this function can be used to store and optionally read out demodulated cd text data, etc. the range of this special area is set by $a7, and can be selected in 8 steps from 32k to 2m bits. table 4-19 shows the addresses which can be specified according to the used dram capacity and the special area setting value. in addition, the address specification method can be selected from absolute and relative specification. 0 0 1 1 rsl 1 0 4m setting 16m setting 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 msl 2 1 0 ? ? ? ? ? ? ? 00000 to 007ff 00000 to 00fff 00000 to 01fff 00000 to 03fff 00000 to 07fff 00000 to 0ffff 00000 to 1ffff ? ? ? ? ? ? ? 00000 to 007ff 00000 to 00fff 00000 to 01fff 00000 to 03fff 00000 to 07fff 00000 to 0ffff 00000 to 1ffff drdr19 to drdr0 specification range table 4-19. ? 147 ?

CXD3048R 5-3. dc offset cancel [avrg (average) measurement and compensation] (see fig. 5-3.) the CXD3048R can measure the averages of rfdc, vc, fe and te and compensate these signals using the measurement results to control the servo effectively. this avrg measurement and compensation is necessary to initialize the CXD3048R, and is able to cancel the dc offset. avrg measurement takes the levels applied to the vc, fe, rfdc and te pins as the digital average values of 256 samples, and then loads these values into each avrg register. the avrg measurement commands are d15 (vclm), d13 (flm), d11 (rflm) and d4 (tclm) of $38. measurement is on when the respective command is set to "1". avrg measurement requires approximately 2.9ms to 5.8ms (when mck = 128fs) after the command is received. the completion of avrg measurement operation can be monitored by the sens pin. (see timing chart 5-2.) monitoring requires that the upper 8 bits of the command register are 38 (h). xlat sens (= xavebsy) max. 1s avrg measurement completed 2.9 to 5.8ms ? 156 ? CXD3048R 5-4. e:f balance adjustment function (see fig. 5-3.) when the disc is rotated with the laser on, and with the fcs (focus) servo on via fcs search, the traverse waveform appears in the te signal due to disc eccentricity. in this condition, the low-frequency component can be extracted from the te signal using the built-in trk hold filter by setting d5 (tblm) of $38 to "1". the extracted low-frequency component is loaded into the trvsc register as a digital value, and the trvsc register value is established when tblm returns to "0". next, setting d2 (tlc2) of $38 to "1" compensates the values obtained from the te and se input pins with the trvsc register value (subtraction), allowing the e:f balance offset to be adjusted. (see fig. 5-3.) 5-5. fcs bias (focus bias) adjustment function the fbias register value can be added to the fcs servo filter input by setting d14 (fbon) of $3a to "1". (see fig. 5-3.) when d11 = 0 and d10 = 1 is set by $34f, the fbias register value can be written using the 9-bit value of d9 to d1 (d9: msb). in addition, the rf jitter can be monitored by setting the $8 command soct to "1". (see "dsp block timing chart".) the fbias register can be used as a counter by setting d13 (fbss) of $3a to "1". the fbias register functions as an up counter when d12 (fbup) of $3a = 1, and as a down counter when d12 (fbup) of $3a = 0. the number of up and down steps can be changed by setting d11 and d10 (fbv1 and fbv0) of $3a. when using the fbias register as a counter, the counter stops when the value set beforehand in fbl9 to fbl1 of $34 matches the fcsbias value. also, if the upper 8 bits of the command register are $3a at this time, sens goes high and the counter stop can be monitored. here, assume the fbias setting value fb9 to fb1 and the fbias limit value fbl9 to fbl1 are set in status a. for example, if command registers fbup = 0, fbv1 = 0, fbv0 = 0 and fbss = 1 are set from this status, down count starts from status a and approaches the set limit value. when the limit value is reached and the fbias value matches fbl9 to fbl1, the counter stops and the sens pin goes high. note that the up/down counter counts at each sampling cycle of the focus servo filter. the number of steps by which the count value changes can be selected from 1, 2, 4 or 8 steps by fbv1 and fbv0. when converted to fe input, 1 step corresponds to 1/512 v dd /2. abc fbias setting value (fb9 to fb1) limit value (fbl9 to fbl1) sens value a: register mode b: counter mode c: counter mode (when stopped) ? 157 ?

CXD3048R 5-6. agcntl (automatic gain control) function the agcntl function automatically adjusts the filter internal gain in order to obtain the appropriate servo loop gain. agcntl not only copes with the sensitivity variation of the actuator and photo diode, etc., but also obtains the optimal gain for each disc. the agcntl command is sent when each servo is turned on. during agcntl operation, if the upper 8 bits of the command register are 38 (h), the completion of agcntl operation can be confirmed by monitoring the sens pin. (see timing chart 5-4 and "description of sens signals".) setting d9 and d8 of $38 to "1" sets fcs (focus) and trk (tracking) respectively to agcntl operation. note) during agcntl operation, each servo filter gain must be normal, and the anti-shock circuit (described hereafter) must be disabled. xlat sens (= agok) max. 11.4s agcntl completion timing chart 5-4. coefficient k13 changes for agf (focus agcntl) and coefficients k23 and k07 change for agt (tracking agcntl) due to agcntl. these coefficients change from 01 to 7f (h), and they must also be set within this range when written externally. after agcntl operation has completed, these coefficient values can be confirmed by reading them out from the sens pin with the serial readout function (described hereafter). agcntl related settings the following settings can be changed with $35, $36 and $37. fg6 to fg0; agf convergence gain setting, effective setting range: 00 to 57 (h) tg6 to tg0; agt convergence gain setting, effective setting range: 00 to 57 (h) ags; self-stop on/off agj; convergence completion judgment time aggf; internally generated sine wave amplitude (agf) aggt; internally generated sine wave amplitude (agt) agv1; agcntl sensitivity 1 (during rough adjustment) agv2; agcntl sensitivity 2 (during fine adjustment) aghs; rough adjustment on/off aght; fine adjustment time note) converging servo loop gain values can be changed with the fg6 to fg0 and tg6 to tg0 setting values. in addition, these setting values must be within the effective setting range. the default settings aim for 0db at 1khz. however, since convergence values vary according to the characteristics of each constituent element of the servo loop, fg and tg values should be set as necessary. ? 159 ? CXD3048R agcntl default operation has two stages. in the first stage, rough adjustment is performed with high sensitivity for a certain period of time (select 256/128ms with aght, when mck = 128fs), and the agcntl coefficient approaches the appropriate value. the sensitivity at this time can be selected from two types with agv1. in the second stage, the agcntl coefficient is finely adjusted with relatively low sensitivity to further approach the appropriate value. the sensitivity for the second stage can be selected from two types with agv2. in the second stage of default operation, when the agcntl coefficient reaches the appropriate value and stops changing, the CXD3048R confirms that the agcntl coefficient has not changed for a certain period of time (select 63/31ms with aghj, when mck = 128fs), and then completes agcntl operation. (self-stop mode) this self-stop mode can be canceled by setting ags to "0". in addition, the first stage is omitted for agcntl operation when aghs is set to "0". an example of agcntl coefficient transitions during agcntl operation with various settings is shown in fig. 5-5. initial value sens agcntl start agcntl completion convergence value agcntl coefficient value slope agv1 aght agj slope agv2 fig. 5-5. note) fig. 5-5 shows the case where the agccntl coefficient converges from the initial value to a smaller value. ? 160 ?

(see fig. 5-11.) the bottom hold speed and mirror sensitivity can be selected from four values using d7 and d6, and d5 and d4, respectively, of $3c. fig. 5-11. dfct signal generation the loaded rf signal is input to two peak hold circuits with different time constants, and the dfct signal is generated by comparing the difference between these two peak hold waveforms with the dfct comparator level.

(see fig. 5-13.) in addition, these operations are activated by the default. they can be disabled by setting d7 (dfsw) of $38 to "1". input register hold register en hold filter servo filter error signal dfct fig. 5-13. 5-11. anti-shock circuit when vibrations occur in the cd player, this circuit forces the trk filter to switch to gain-up mode so that the servo does not become easily dislocated. this circuit is for systems which require vibration countermeasures. concretely, vibrations are detected using an internal anti-shock filter and comparator circuit, and the gain is increased. (see fig. 5-14.) the comparator level is fixed to 1/16 of the maximum comparator input amplitude. however, the comparator level is practically variable by adjusting the value of the anti-shock filter output coefficient k35. this function can be turned on and off by d19 of $1 when the brake circuit (described hereafter) is off. (see table 5-17.) this circuit can also support an external vibration detection circuit, and can set the trk servo filter to gain-up mode by inputting high level to the atsk pin. when the upper 4 bits of the command register are 1 (h), vibration detection can be monitored from the sens pin. it can also be monitored from the atsk pin by setting $3f command asot to "1". te anti-shock filter trk gain-up filter trk gain normal filter trk pwm gen. atsk sens comparator fig. 5-14. ? 164 ? CXD3048R 5-12. brake circuit immediately after a long distance track jump it tends to be hard for the actuator to settle and for the servo to turn on. the brake circuit prevents these phenomenon. in principle, the brake circuit uses the tracking drive as a brake by cutting the unnecessary portions utilizing the 180 offset in the rf envelope and tracking error phase relationship which occurs when the actuator traverses the track in the radial direction from the inner track to the outer track and vice versa. (see figs. 5-15 and 5-16.) concretely, this operation is achieved by masking the tracking drive using the trkcncl signal generated by loading the mirr signal at the edge of the tzc (tracking zero cross) signal. the brake circuit can be turned on and off by d18 of $1. (see table 5-17.) in addition, the low frequency for the tracking drive after masking can be boosted.

CXD3048R 5-13. cout signal the cout signal is output to count the number of tracks during traverse, etc. it is basically generated by loading the mirr signal at both edges of the tzc signal. the used tzc signal can be selected from among three different phases according to the cout signal application. hptzc: for 1-track jumps fast phase cout signal generation with a fast phase tzc signal. (the tzc phase is advanced by a cut-off 1khz digital hpf; when mck = 128fs.) stzc: for cout generation when mirr is externally input and for applications other than cout generation. this is generated by sampling the te signal at 700khz. (when mck = 128fs) dtzc: for high-speed traverse reliable cout signal generation with a delayed phase stzc signal. since it takes some time to generate the mirr signal, it is necessary to delay the tzc signal in accordance with the mirr signal delay during high-speed traverse. the cout signal output method is switched with d15 and d14 of $3c. when d15 = 1: stzc when d15 = 0 and d14 = 0: hptzc when d15 = 0 and d14 = 1: dtzc when dtzc is selected, the delay can be selected from two values with d14 of $36. 5-14. serial readout circuit the measurement and adjustment results specified beforehand by serial command $39 can be read out from the sens pin by inputting the readout clock to the sclk pin.

(the coefficient ram cannot be rewritten during this period.) after that, the characteristics of each built-in filter can be finely adjusted by rewriting the data for each address of the coefficient ram. the coefficient rewrite command is comprised of 24 bits, with d14 to d8 of $34 as the address (d15 = 0) and d7 to d0 as the data. coefficient rewriting is completed 11.3s (when mck = 128fs) after the command is received. when rewriting multiple coefficients continuously, be sure to wait 11.3s (when mck = 128fs) before sending the next rewrite command. 5-16. pwm output fcs, trk and sld pwm format outputs are described below. in particular, fcs and trk use a double oversampling noise shaper. timing chart 5-20 and fig. 5-21 show examples of output waveforms and drive circuits. 64t mck 64t mck 64t mck at mck at mck sfdr srdr sld 32t mck 32t mck 32t mck 32t mck 32t mck 32t mck fcs/trk ffdr/ tfdr frdr/ trdr output value +a output value ?a output value 0 t mck a 2 t mck a 2 t mck a 2 t mck a 2 mck (5.6448mhz) timing chart 5-20. fig. 5-21. drive circuit r r r r v ee drv v cc rdr fdr t mck = 180ns 1 5.6448mhz ? 167 ?
