Monolithic Linear IC

LA9230M/9231M

Analog Signal Processor (ASP)

for CD players

Overview

The LA9230M and LA9231M are analog signal processing and

servo control bipolar ICs designed for use in compact disc

players; a compact disc player can be configured by combining

these ICs, a CD-DSP such as the LC78620E, and a small

number of additional components. The differences between the

LA9230M and the LA9231M are that the LA9231M: (1) has a

focus search time that is four times faster; (2) has an additional

capacitor pin for focus search smoothing; (3) and can disable

output of the track-kick signal during EF balance adjustment.
