Overview: For Audio Equipment MN662740RE
Signal Processing LSI for CD Players
Overview
The MN662740RE is a CD signal processing LSI that, on a single chip, bines 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%) Guaranteed operation for double-speed playback except for D/A converter output and 4 fs mode serial output Operating voltage 3.0 to 5.
