CMOS LSI
LC78631E pact Disk Player DSP
Overview
The LC78631E is a pact disc D/A signal-processing LSI for CD-ROM drives that provides a variable clock error correction (VCEC) mode. The LC78631E demodulates the EFM signal from the optical pickup and performs de-interleaving, error detection, error correction, digital filtering, and other processing. The LC78631E includes an on-chip 1-bit D/A converter, and executes mands sent from a control microprocessor.
