Overview

The LC78628E CMOS IC implements signal processing and servo control for compact disc players, laser disc players, CD-V, CD-I, and similar products. It provides functions for demodulation of the EFM signal from the optical pickup, deinterleaving, error detection and correction, and processing servo system commands issued by the system microprocessor. In addition to this basic CD functionality, it also provides HDCD (High Definition Compatible Digital) decoding functions and CD text functions. It also includes a built-in EFM PLL circuit.
