Philips Semiconductors
Preliminary specification
Analog current buffer for CD-R and CD-RW
systems
TZA1027
FEATURES
Eight amplifiers for servo and power calibration
functions
Gain selector for CD-R and CD-RW discs
Separate data amplifier for read speed up to thirty times
nominal data speed.
GENERAL DESCRIPTION
The TZA1027 is an analog current buffer IC for CD-R and
CD-RW systems with a 3-spot push-pull tracking system.
The IC interfaces directly to the photo diodes and
TZA1020. A HF current amplifier is implemented to detect
the actual HF data signal.
