MN662710RA
Signal Processing LSI for CD Players
on a single chip, combines 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.
processing LSI for double-speed CD-ROM playback. Do
not, however, use the audio equipment D/A converter
during double-speed playback.
