Monolithic Linear IC

LA9220M

Analog Signal Processor Circuit (ASP)

for CD Players

Overview

The LA9220M 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, a CD-DSP such as the LC78681KE, and a small

number of additional components.

Functions

I/V amplifier, RF amplifier (with AGC), SLC, APC, VCOC

amplifier, VCO (supports double-speed playback), FE, TE

(with VCA and auto-balance function), tracking servo am-

plifier (with offset cancellation function), spindle servo

amplifier (with gain switching function), sled servo ampli-

fier (with off function), focus detection (DRF, FZD), track

detection (HFL, TES), defect detection, and shock detec-

tion.

Features

The following automatic adjustment functions are built in.

• Focus offset auto cancel.

• Tracking offset auto cancel.

• EF balance auto adjustment.

• RF level AGC function.

• Tracking servo gain RF level following function.
