LC7872E Overview
EN4868A CMOS LSI LC7872E CD Graphics Decoder Overview The LC7872E is a CMOS LSI that integrates in a single chip the signal processing functions required for pact disk graphics (CD-G) decoding. The LC7872E accepts the subcode R to W signals output by a CD-DSP chip such as the Sanyo LC786X series, LC7862XE series or LC7863XE series and performs de-interleaving, error detection and correction, graphics instruction...
