MN662747RPH
Signal Processing LSI for CD Players
Overview
The MN662747RPH is a CD signal processing LSI that,
on a single chip, combines 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.
Features
