Overview
The LC78681KE and LC78681KE-L are signal processing and servo control CMOS LSIs for compact disk players, laser disk players, CD-V, CD-I and similar applications. These products provide a rich set of signal processing functions, including demodulation of the EFM signal from the optical pickup, de-interleaving, error detection and correction, and digital filter functions that can contribute to end product cost reduction. These LSIs also process servo system commands sent from a control microprocessor. They can be directly interfaced to a serial input DAC (such as the Sanyo LC78835K or LC78855K) that provides built-in dedicated digital filters.
