MN662740RE : For Audio Equipment 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 play.
