GENERAL DESCRIPTION
TZA1020 (AEGER2) is an analog pre-processor IC for
CD-R and CD-RW systems with 3-spots push-pull tracking
system. The IC interfaces directly to the photo diodes.
The device generates signals for laser power calibration
and laser power control during disc writing. Normalized
error signals are generated for servo control and wobble
detection. An HF current amplifier is implemented to
detect the actual HF data signal. The Fast Track Count
(FTC) amplifier generates a radial error signal to allow fast
track counting.
TZA1020A (AEGER2A) is similar to the TZA1020, except
for non-clamped MIRN, which allows operation with
IGUANA.
