MN662785TBUC
1. TYPE
Signal processing integrated circuit for CDs (Compact Discs)
2. OVERVIEW
MN662785TBUC is a signal processing IC for CDs. It incorporates optical servo (focus, tracking,
and traverse servos) processing function, digital signal processing function (EFM demodulation and
error correction), digital servo processing function for spindle motor, anti-shock memory control
function for 16M, 4M, or 1M DRAM in compression or decompression mode available to disc
rotation synchronous playback (jitter-free), a digital filter, and D/A converter. All the processing
functions after the head amplifier (RF amplifier) are incorporated into a single chip.
3. FUNCTIONS AND FEATURES
