2000 oct 30 7 philips semiconductors product speci?cation pre-ampli?ers for cd-rw systems tza1020; tza1020a 7 functional description all functions are designed in such a way that a read speed up to twelve times nominal speed is possible (n = 1, 2, 4, 8 or 12). recording speed up to four is possible (n = 1, 2 or 4). the maximum recording speed must be determined. 7.1 data ampli?er the central diodes currents (c1 to c4) are fed to a high bandwidth current amplifier. the gain of the current amplifier can be switched by means of the i 2 c-bus microcontroller interface to compensate for differences in cd-r and cd-rw disc reflection. data signals up to twelve times nominal data speed can be read. 7.2 normalizer the currents from the central diodes (c1 to c4), the current from the satellite diodes (sa1, sa2, sb1 and sb2) and the laser set-point current (cagain) are (optionally sampled) fed to the first low-pass filters with a bandwidth of 60 khz. the normalizing circuit generates error signals for servo control that are independent of the diode current level. the gain of the error signals is controlled by the i 2 c-bus microcontroller interface. a dropout concealment becomes active if the input current level is below a certain threshold value. this threshold value is also controlled by the i 2 c-bus. 7.3 wobble pre-processor the wobble signal of the pre-groove is detected by means of the ppn signal. the currents from inputs c1 to c4 are filtered and processed to provide optimal signal-to-noise ratio. the bandwidth of the filter may be adapted to the disc speed via the i 2 c-bus. the bandwidth of a noise reduction loop is controlled by an external capacitor, the i 2 c-bus interface controls the total operation of the processor. 7.4 beta detector the beta detector generates signals necessary for the symmetry detection of the hf signal. by measuring peak values (a1 and a2) and average value of the signal (calf), an optimum laser writing power can be determined. the gain of the measured values is controlled by the i 2 c-bus. the time constant of the peak detectors and bandwidth of the low-pass filtered aperture signal can also be adapted to the disc speed by the i 2 c-bus. 7.5 alpha detector the alpha detector determines a parameter called alpha during disc writing. alpha must be kept constant to allow recording over a fingerprint or black dot. the definition of alpha is different for cd-r and cd-rw; for cd-r the light absorption of the disc is measured, for cd-rw alpha is determined by actual laser power and disc reflection. the gain of the measured signals and the cd-r and cd-rw selection is performed by the i 2 c-bus. 7.6 fast track count the fast track count circuit generates a radial error (re) signal for fast track counting. a gain switch compensates for difference in cd-r and cd-rw disc reflection. 7.7 spot position measurement to allow alignment of photo diodes via the tza1020, a number of linear combinations of input currents can be realized (meas1 and meas2). selection of the actual combination is performed by the i 2 c-bus.
2000 oct 30 8 philips semiconductors product speci?cation pre-ampli?ers for cd-rw systems tza1020; tza1020a 8i 2 c-bus protocol 8.1 addressing and data bytes full control of the tza1020 is accomplished via the 2-wire i 2 c-bus. up to 400 kbits/s bus speed can be used in accordance with the i 2 c-bus fast-mode specification. for programming the device (write mode) eight data byte registers are available/addressable via eight subaddresses. automatic subaddress incrementing enables the writing of successive data bytes in one transmission. during power-on, data byte registers are reset to a default state by use of a power-on reset (por) circuit whose signal is derived from the internally generated i 2 c-bus supply voltage (v ss1 ). for reading from the device (read mode) one data byte register is available without subaddressing. 8.1.1 w rite mode table 1 slave address; 34h table 2 subaddress 00h to 07h note 1. the use of subaddresses f0h to f7h (11110xxx) instead of 00h to 07h (00000xxx) disables the automatic subaddress incrementing allowing continuous writing to a single data byte register (e.g. dac testing). table 3 overview of subaddresses 8.1.2 r ead mode table 4 slave address; 35h table 5 read byte notes 1. in read mode the actual por status can be read. 2. the state of unused read bits should not be relied upon; their state may be changed during development. slave address 0 0 1 1 0 1 0 0 subaddress 0 (1) 0 (1) 0 (1) 0 (1) 0 0/1 0/1 0/1 sub addr por state data bytes 00h 00000000 alphactr2 alphactr1 alphactr0 alphagain4 alphagain3 alphagain2 alphagain1 alphagain0 01h 00000000 free algctr6 algctr5 algctr4 algct3 algctr2 algctr1 algctr0 02h 00000000 tlngain1 tlngain0 rengain negain4 negain3 negain2 negain1 negain0 03h 00000000 tmdac tlnlim1 tlnlim0 sumref4 sumref3 sumref2 sumref1 sumref0 04h 00000000 sd?ne7 sd?ne6 sd?ne5 sd?ne4 sd?ne3 sd?ne2 sd?ne1 sd?ne0 05h 00011111 lexton betactrl1 betactrl0 betascl4 betascl3 betascl2 betascl1 betascl0 06h 01100000 free ppnctrl1 ppnctrl0 ppnscl4 ppnscl3 ppnscl2 ppnscl1 ppnscl0 07h 00000000 porr free urefsel cdrwsel lpsel1 lpsel0 meassel1 meassel0 slave address 0 0 1 1 0 1 0 1 read byte por (1) 0 (2) 0 (2) 0 (2) 0 (2) 0 (2) 0 (2) 0 (2)

2000 oct 30 33 philips semiconductors product speci?cation pre-ampli?ers for cd-rw systems tza1020; tza1020a 14 soldering 14.1 introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. 14.2 re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. 14.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 14.4 manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
2000 oct 30 34 philips semiconductors product speci?cation pre-ampli?ers for cd-rw systems tza1020; tza1020a 14.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package soldering method wave reflow (1) bga, sqfp not suitable suitable hlqfp, hsqfp, hsop, htssop, sms not suitable (2) suitable plcc (3) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (3)(4) suitable ssop, tssop, vso not recommended (5) suitable
