Front end for CD players

BA6354BFS

The BA6354BFS is an analog front end LSI developed for CD players and CD-ROMs.
With a shared equalizer for normal and multiple speeds, and an input stage that supports hologram picks, the need for
external components is minimized and the package size is greatly reduced.

Applications

CD players, car navigation CD-ROMs

Features

1) Supports hologram picks.
2) Internal APC circuit for laser control.
3) DC control enables balance adjustment for focus er-

ror and tracking error.

4) Maintains the output amplitude at a constant value

with an RF AGC circuit.

5) Switchable equalizer (internal normal speed and

multiple speed equalizer).
