CMOS LSI
LC78624E
Compact Disc Player DSP
Overview
The LC78624E is a
CMOS LSI that implements the signal processing and servo control required by compact disc players.
Including an EFM-PLL and text decoder, the LC78624E strictly limits functionality to basic signal processing and servo system operation to achieve the best cost-performance balance for low-end players.
As basic functions, the LC78624E provides demodulation of the EFM signal from the optical pickup, de-interleaving, error detection and correction, and processes servo commands sent from the control microcontroller.
Functions
• Input signal processing: The LC78624E takes an HF signal as input, digitiz...
