GENERAL DESCRIPTION The TZA1026 is a data amplifier and laser supply circuit for voltage output mechanisms found in a wide range of audio and video CD systems. The device contains an RF amplifier and an automatic laser power control circuit. The preamplifier forms a versatile, programmable interface for voltage output CD mechanisms to the Philips' digital signal processor CD10Auto (SAA7326).
TZA1026
The RF bandwidth allows this device to be used in CD-A/V and CD-R/W applications with a data rate up to a maximum of n = 4 times speed. The RF gain can be adapted for CD-A/V discs or CD-R/W discs by means of the gain select signal. The equalizer can be adjusted for n = 1 or n = 2 times speed with the equalizer/speed select signal. For n = 4 times speed the RF is not equalized. The TZA1026 can be adapted to a wide range of voltage output mechanisms by means of external resistors. The ALPC circuit will maintain control over the laser diode current. With an on-chip reference voltage generator, a constant and stabilized output power is ensured independent of ageing. The ALPC can accommodate N- or P-substrate monitor diodes. A separate supply voltage connection for the laser allows the internal power dissipation to be reduced by connecting a low voltage supply. The laser output current range can be optimized to fit the requirements of the laser diode by means of one external resistor. When a DC-to-DC converter is used, in combination with the control loop of the ALPC, the adjustable output current range provides the possibility to compensate for the extra gain a DC-to-DC converter introduces in the control loop.

TZA1026
The gain of the RF amplifier can be adjusted by the external input resistors. Fig.3 shows the simplified schematic which can be used to determine the RF gain. The signal is AC coupled to the RF amplifier. The formula to determine the gain is shown below: Z tr ( RF ) G RF = - n x -----------------(1) R2 where: GRF is the RF amplifier gain n is the number of input resistors Ztr(RF) is the transimpedance of the amplifier () R2 is the value of the input resistors(). The gain can be increased by a factor 4 by making pin CDRW HIGH. The value of Ztr(RF) is 9.8 k for CD-A/V (CDRW = LOW) and 38 k for CD-R/W (CDRW = HIGH). The equalizer/bandwidth section can be switched between n = 1, n = 2 (inclusive the corresponding equalizer) or n = 4 (inclusive the required bandwidth limitation) times speed. The DC output level of the amplifier can be set by applying a DC voltage on the common mode feedback pin CMFB. Since the input signal is AC-coupled the RF output voltage will swing (symmetrically) around this DC level. The coupling of the TZA1026 to the signal processor (SAA7326) can be either AC or DC. When an AC-coupling is chosen (see Fig.8) the minimum supply voltage can be applied. When a DC-coupling is chosen (see Fig.9) a minimum supply voltage of 2.8 V is required.

Automatic laser power control circuit The ALPC stabilises the laser output power thereby reducing the effect of ageing of the laser. The TZA1026 automatically detects when an N- or P-substrate monitor diode is used and selects the correct reference voltage. A simplified diagram for the use of an N- or P-substrate monitor diode is given in Fig.4. The gain of the loop can be controlled (reduced) by adding an external resistor between pins RGADJ and GND. The loop gain then becomes: 250 G loop = G ALPC x G lm x G con x -----------------------------------(2) 250 + R RGADJ where: Gloop is the loop gain GALPC is the ALPC transfer (60 A/V) Glm is the laser-to-monitor transfer (V/A) Gcon is the extra gain introduced when a DC-to-DC converter is used in the loop; Gcon = 1 when no DC-to-DC converter is used 250 is a fixed internal resistor value () RRGADJ is the value of the external resistor (). The minimum available output current is also reduced when an external resistor is used. The formula to determine the minimum available output current is shown in equation (3). 250 (3) I o = I o(LASER)(max) x -----------------------------------250 + R RGADJ where: Io is output current (mA)
TZA1026
Io(LASER)(max) is the maximum laser output current (mA) 250 is a fixed internal resistor value () RRGADJ is the value of the external resistor (). The bandwidth of the loop is determined by the external filter capacitor CCFIL and the loop gain. The formula to determine the bandwidth is shown in equation (4). -3dB C CFIL x 16 10 = ----------------------------------------G loop

where: CCFIL is the value of the capacitor (F) Gloop is the loop gain. The TZA1026 has a protection circuit to prevent laser damage that can occur due to a dip of VDD(L). When a dip occurs the output transistor (see Fig.4) will go into saturation making it unable to supply the required laser current. Without the protection circuit the ALPC would still try to supply the required laser current by charging the filter capacitor CCFIL. After the dip a fully charged capacitor would create a large output current during the few milliseconds it needs to discharge the capacitor to a normal level. The protection circuit monitors the output transistor and switches off the ALPC when saturation occurs by discharging the capacitor. The ALPC will automatically restart within a few milliseconds after the dip has passed.

7. An external resistor can be used to reduce the maximum output current (and the gain) of the laser supply; see equation (4). 8. The output impedance strongly depends on the drop voltage (Vdrop).

10. When a voltage dip at VDD(L) occurs it could cause peak currents on Io(LASER) coming out of the ALPC output. To protect the laser against such peak currents a protection circuit will switch-off the laser current when Vdrop becomes lower than Vclamp. When Vdrop > Vclamp the laser will switch-on automatically again. 11. The pin EQSEL is a three level switch. When this pin is left open-circuit two internal resistors will keep the pin EQSEL at 12VDD. This is the n = 4 times speed state. The two internal resistors are non-linear (when EQSEL = HIGH or LOW the input or output current will be limited).

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. 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" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all SO packages. 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 techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering
TZA1026
Wave soldering techniques can be used for all SO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. 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. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. 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. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) 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.
