Signal Processing LSI for CD Players
Overview
The MN662741RH 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),
digital servo processing for the spindle motor, digital fil-
ter, and D/A converter, so thus covers all signal process-
ing functions from the head's RF amplifier onward.
