MN662740RE

Signal Processing LSI for CD Players

Overview

The MN662740RE is a CD signal processing LSI that,

on a single chip, combines an optics servo for the CD

player (focus, tracking, and traverse servos), digital signal

processing (EFM demodulation and error correction),

digital servo processing for the spindle motor, digital

filter, and D/A converter, so thus covers all signal

processing functions from the head's RF amplifier onward.

(Spindle motor servo)

CLV digital servo

(Audio circuits)

Digital filter using 8-fold oversampling

Built-in D/A converter (1-bit D/A converter)

Built-in differential operational amplifier (2nd order

low pass filter)

(Other)

Built-in playback pitch control function (±13%)

Guaranteed operation for double-speed playback

except for D/A converter output and 4 f

mode serial

output

Operating voltage 3.0 to 5.5V

Features

(Optics servo)

Frame synchronization detection, holding, and insertion

Subcode data processing

Q data CRC check

Built-in Q data register

CIRC error detection and correction

C1 decoder: duplex error correction

C2 decoder: triplex error correction

Built-in 16-K bits of RAM for de-interleaving
