GENERAL DESCRIPTION
The TZA1031 is an analog preprocessor IC for recording
CD and DVD systems such as DVDRW, combo and
double writer applications. It is optimized to work with the
optical pick-up unit preprocessor IC TZA1030 and Philips
decoder ICs HDR65 and IGUANA. The TZA1031 takes
care of the specific recording functions in the servo,
RF and push-pull channels. It also provides read-out of
BCA code.
