Analog Signal Processor (ASP)

for CD players

Overview

The LA9241M 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.
