For Audio Equipment
MN662724RPE
Signal Processing LSI for CD Players
Overview
The MN662724RPE 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 sig-
nal processing (EFM demodulation and error correction),
and digital servo processing for the spindle motor.
