CMOS LSI
LC78622E pact Disc Player DSP
Overview
The LC78622E is a CMOS LSI that implements the signal processing and servo control required by pact disc players. At the same time as providing an EFM PLL circuit, a 1-bit D/A converter, and an analog low-pass filter the LC78622E realizes an optimal cost-performance tradeoff for low-end players by strictly limiting functionality to basic signal-processing and servo system functionality. The LC78622E signal-processing system provides demodulation of the EFM signal from the pickup, de-interleaving, error detection and correction, and digital filters that can prove useful in reducing the cost of end products....
