Overview
The LA9605W integrates MiniDisk playback functions,
including servo error signal generation, RF signal
processing, and wobble signal binarization output on a
single chip. The LA9605W, when combined with an
LC89640, can implement a complete MD player system.
Features
Allows the servo error signal level to be set to an
arbitrary level using a VCA circuit.
Few peripheral components required.
