dvd player digital servo & dsp ic s5l 1454a 1 introduction ks1454 is a dvdp (digital video disc player) 1-chip lsi which includes the digital servo and dsp(digital signal processor) features. servo block performs the digital servo function, which controls disc speed and pick-up location as it retrieves signals from the disc (cd,vcd,dvd). servo block contains the wide capture pll. dsp block receives the efm signal as an input and performs buffer control for demodulated data output while efm demodulation and error corrections are being carried out. features micom ? 8bit parallel interface ? built-in direct memory access (dvd/cd) pll ? built-in wide capture range ( 50%) pll ? built-in efm slice ? built-in f/v converter for rf eq adjustment of dac method ? charge-pump pwm control method ? fd/pd gain ad justment ? built-in wide range vco(20 - 100mhz) servo ? cd/cd-rom 1,2x, dvd 1x compatible digital servo ic. ? complete automatic adjusting feature. (focus/tracking loop's input gain, offset, balance, loop gain) ? each servo loop has a digital filter, reducing the number of external parts. ? built-in agc feature that responds optimally to various disc types. ? high speed moving control(built-in sled fg encoder). ? built-in speed controlling search algorithm. ? built-in 10bit a/d converter and 10bit d/a con verter. ? various filter characteristics and internal constants can be set from micom. ? built-in defect and shock response. ? built-in 16bit track counter. ? chooses the best method from multiple search algorithm. ? servo operation improved by widening the range through high speed sampling of 151.2khz

dvd player digital servo & dsp ic s5l 1454a 41 operation description ? position sensor and track count me thod : when the multiple n-s magnetic poles attached along the sled deceleration gear's cylinder starts to rotate by sled motor operation, the 2 hall sensors with the 90 phase angle detects the magnetic change and outputs a voltage in sine wave form. also, this signal is changed into a logic signal in the comparator, and is input to the dssp's status input as ps0 and ps1. the tolerance for the phase angle 90 is decided by the mechanical location, and if it is accurate, 4 fg edges are made in the ps0 and ps1's 1cycle. the number of trks per fg pulse can be calculated by deck mechanisms such as the number of magnetic poles, etc. the value can be stored in the entc register by micom. when the fg edge is detected according to sled move, the s/w counter ( stcnt) increases by entc, and you can measure the number of trks moved even without h.ct operation. ps1 fgjsp skckd t_avrg jstbl vref trd sld sl_avrg vref skckd ps0 ? sled kick/brake output : (1) waveform : the sled kick pulse is the sld output average value before the move ( sl_avrg), overlapped with the sled kick level ( skckd) and output to sld. the sled kick pulse reverts to brake when the stcnt becomes the reverse count value found by move trk number (n)* sl_k. at this time, the brake level is the same as the kick level ( skckd), but while the kick's point of reference is sl_avrg, that of brake is vref. this is because the average output level before and after a move is different for long-distance moves. there isn't that much change in the lens shift in short movements in the level of track jump, so the kick/brake and stabilization area's output reference level are both sl_avrg ( trd_avrg). but in long-distance moves, the lens is at the midpoint, so there is no more meaning for the output average after kick. therefore, the trd output during sled kick/brake and stabilization area are held at vref instead of trd_avg, and off status is maintained. (2) limit function for emergencies during kick/brake : unlike track jump using mirr/tzc, ps0 and ps1 have almost no chance of an output error due to circuitry reasons, apart from the damage of the hall sensor or comparator. however, there is a chance of kick time becoming very long, or getting trapped in an endless kick when the load on the sled becomes abnormally large. to prevent this, there is an emergency detection timer ( psstp) that stops the move and changes to pull-in mode when the ps edge doesn't come out within a specific length of time.
S5L1454A dvd pla yer digital servo & dsp ic 42 ? move end and stable period: (1) brake end : in the deceleration area, if the interval between the fg pulse period is longer than the time set by micom ( fgjsp), or the movement direction is incorrect, the sld output is set back to vref and the brake is stopped. (2) stabilization area : the sld output is held to vref for the stabilization area set by micom. trd also maintains vref status. when the stabilization area comes to an end, it diverges into the trsv routine within the fon_int, and attempts normal tracking/sled pull-in. oo speed control track jump & sled move speed control track jump summary speed control track jump is a track jump method that moves the p/u's lens. the number of tracks to be jumped can be set between 1 and 255. the speed control kick detects the p/u lens'speed in relation to the disc using the track error and mirr signals from the disc, and controls the trd kick signal so that it matches the dsp speed profile. you can select the tm_win to reduce tzc errors such as glitches generated by initial kicks. when tracking is on, lens brake and loop gain up periods can be selected. initialize when inicmd's tkjm is set to h and jpmcmd is received, speed control track jump is carried out for the number of tracks set by command. other initial conditions are the same as those described in track jump using kick/brake.
