For Audio Equipment MN662747RPH Signal Processing LSI for CD Players Overview The MN662747RPH is a CD signal processing LSI that, on a single chip, combines optics servos 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.
(Audio circuits) Digital filter using 8-fold oversampling Built-in D/A converter (1-bit D/A converter) Built-in differential operational amplifier (secondary low pass filter) (Other) Built-in playback pitch control function (normal spee...
