TZA1026 Data Amplifier And Laser Supply Circuit For CD Audio And Video Optical Systems (ADALASAuto)

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 versatileprogrammable Interface for voltage output CD mechanisms to the Philips, digital signal processor CD10Auto SAA7326 . 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 generatora 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 usedin 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.
