GENERAL DESCRIPTION
The TZA1035HL 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 CD
Differential phase detector for DVD
Push-pull with flexible left and right weighting to
compensate dynamic offsets e.g. beam landing offset
A 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.
