TZA1038HW High Speed Advanced Analog DVD Signal Processor And Laser Supply

The TZA1038HW is an Analog preprocessor and laser supply circuit for DVD and CD read-only players. The device contains data Amplifiers several options for radial tracking and focus control. The preamplifier forms a versatile, programmable Interface between single light path voltage output CD or DVD mechanisms to Philips digital signal processor family for CD and DVD (for example, Gecko, HDR65 or Iguana). A separate high-speed RFSUM input is available.The device contains several options for radial tracking:Conventional three-beam tracking for CDDifferential phase detector for DVDPush-pull with flexible left and right weighting to compensate dynamic offsets e.g. beam landing offsetA radial error signal to allow Fast Track Count (FTC) during track jumps.The dynamic range of this preamplifier and processor combination CAN be optimized for LF servo and RF data paths. The gain in both channels CAN be programmed separately and so guarantees optimal playability for all disc types.The RF path is fully DC coupled. The DC content compensation techniques provide fast settling after disc errors.The device CAN accommodate astigmatic, single foucault and double foucault detectors and CAN be used with P-type lasers with N-sub or P-sub monitor Diodes After an initial adjustment, the circuit will maintain control over the Laser Diode current. With an on-chip reference voltage generator, a constant stabilized output power is ensured and is independent of ageing.An internal Power-on reset circuit ensures a safe start-up condition.
