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.
