CMOS LSI
LC7874E
CD Graphics Decorder
Overview
The LC7874E is a CMOS LSI that provides the signal processing needed for compact 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.
• Has microcomputer interface functions, allowing set upgrading. • Provides superimposition support. • Has a color bar signal output function. • DRAM interface and RGB output and sync signal output are 3-state outputs.
