LC78626E
DSP for Compact Disk Players
Overview
The LC78626E is a monolithic compact disk player signal processing and servo control CMOS IC equipped with an internal anti-shock control function. Designed for total functionality including support for EFM-PLL, and one-bit D, A converter, and containing analog low-pass filter, the LC78626E provides optimal cost-performance for low-end CD players that provide anti-shock systems. The basic functions provided by this IC include modulation of the EFM signal from the optical pick-up, deinterleaving, detection and correction of signal errors, prevention of a maximum of approximately 10 seconds of skipping, signal processing such as digital filtering (which is useful in reducing the cost of the player), and processing of a variety of servo-related commands from the microprocessor.
After the subcode Q signal passes the CRC check, it is output to the microprocessor through a serial transmission (LSB first). .
