General Description
LC78681E General Description
The LC78681E is a CMOS LSI providing digital signal processing (DSP) and servo control for compact disc players and other audio devices, including laser disc players and equipment using compact disc video (CD-V) and compact disc interactive (CD-I) formats. Functions include the demodulation of EFM (eight-tofourteen modulation) signals from optical pickups, deinterleaving, detection and correction of error signals, and signal processing for digital filters as well as other features that can help reduce player cost. The LC78681E also processes commands from the microprocessor for the servo system. Direct interface is also possible with the Sanyo LC7883K and LC78835, which are serial input D/A converters with on-chip digital filters.
