MN662741RH
Signal Processing LSI for CD Players
Overview
The MN662741RH 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%) Operating voltage 4.0 to 5.
