MN662724RPE

Signal Processing LSI for CD Players

Overview

The MN662724RPE 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), and digital servo processing for the spindle motor.

Features

(Optics servo)

Focus, tracking, and traverse servos Automatic adjustment functions for FO/TR gain, FO/TR offset, and FO/TR balance Built-in D/A converter for drive voltage output Built-in dropout countermeasures Anti-shock functions Built-in track cross counter

(Other)

Built-in playback pitch control function (normal speed only)(±13%) Built-in support for jitter-free disc rotation synchronization playback Oscillator shutdown mode Power management mode

Operating voltage 4.5 to 5.5V

Applications
