Overview: For Audio Equipment MN662747RPH
Signal Processing LSI for CD Players
Overview
The MN662747RPH is a CD signal processing LSI that, on a single chip, bines 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 speed only) (± 13%) Support for quadruple-speed playback (digital servo and signal processing block only) Built-in support for jitter-free disc rotation synchronization playback Oscillator shutdown mode Power management mode Operating voltage 4.5 to 5.
