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.
