Sanyo Electric LC78630E
The LC78630E is a CD-DA signal-processing LSI for use in video CD player systems. The LC78630E incorporates signal-processing circuits for demodulating and deinterleaving the EFM signal from the optical pickup, error detection and correction, and digital filtering. It also includes a 1-bit D/A converter and executes commands sent from a system control microprocessor.| Part No. | LC78630E |
