Overview
Compact Disc Player DSP with Built-in Microcontroller
The LC78605E CMOS IC implements the signal processing, servo control, LCD display, button state acquisition, and remote controller handling required by compact disc players without requiring a separate microcontroller. It provides the following basic functions: demodulation of the EFM signal from the optical pickup, deinterleaving, error detection and correction, 8× oversampling audio filters, D/A converter (with built-in analog low-pass filter), LCD display drivers, key acquisition (A/D) and control processing, and automatic discrimination and playback of CD-RW discs.
