Sanyo Electric LC7874E

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. Package Dimensions unit: mm Features • A CD-G decoder can be configured using a three-chip combination of this LSI—the LC7874E—with external RAM (64K × 4 bits) and an LC78010E digital RGB encoder.
