Monolithic Linear IC

Analog Signal Processor (ASP)

for CD Players

Ordering number:ENN7097

LA9242M

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN

Overview

The LA9242M 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 LC78922E and
LC78620E, with a small number of additional components
required. In addition, this IC allows CD-RW disk playback
due to the on-chip gain switching function.

Functions

I/V amplifier, RF amplifier (with AGC), SLC, APC, FE,
TE (with VCA and auto-balance function), focus serv o am­plifier (with offset cancellation function), spindle serv o am­plifier (with gain switching function), sled servo ampli­fier (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 : FE (pin 20)

• Tracking offset auto cancel : TE (pin 7).

• EF balance auto adjustment.

• RF level AGC function.

• Tracking servo gain RF level following function.

• Focus search smoothing setting pin : FSC (pin 46)

• EF balance adjustment variable range setting pin : (pin

47)

• Focus search mode switching pin : (pin 55)

• Play disc (Normal, CD-RW) mode switching pin : (pin

38)
