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.
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 de-
interleave error signals.
• Has two crystal oscillators, for NTSC and PAL, with
simple switchover by means of a control pin.
Connecting a crystal resonator of 14.31818 MHz for
NTSC and 17.734476 MHz for PAL enables the
standard clock and other necessary timings to be
generated internally.
• Performs CD graphics instruction processing and
drawing functions, and controls image display.
• 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.
