LC7874E Overview
EN5521 CMOS LSI LC7874E CD Graphics Decorder Overview The LC7874E is a CMOS LSI that provides the signal processing needed for pact disc graphics (CD-G) on a single chip. The LC7874E accepts subcode R to W signals output from a CD player DSP LC786X Series, LC7862XE Series, or LC7863XE Series device, and performs de-interleaving, error detection and correction, graphic instruction processing, and image processing....
