The MN662710RA 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 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. The MN662710RA is also usable as a CD signal processing LSI for double-speed CD-ROM playback. Do not, however, use the audio equipment D/A converter during double-speed playback.
