Analog Signal Processor (ASP)
for CD players
Overview
The LA9240M is an analog signal processing and servo control
bipolar IC designed for use in compact disc players; a compact
disc player can be configured by combining this IC with a
CD-DSP such as the LC78622E and LC78620E, with a small
number of additional components required.
Functions
I/V amplifier, RF amplifier (with AGC), SLC, APC, FE, TE
(with VCA and auto-balance function), focus servo amplifier
(with offset cancellation function), tracking servo amplifier
(with offset cancellation function), spindle servo amplifier
(with gain switching function), sled servo amplifier (with off
function), focus detection (DRF, FZD), track detection (HFL,
TES), defect detection, and shock detection.
