Overview
Ordering number : EN5521 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.
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.
• Performs insertion and protection of CD subcode R to W sync signals and detection of R to W signal deinterleave error signals.
• Has two c...
