CD Graphics Decoder
LC7872E
CMOS LSI
Overview
The LC7872E is a CMOS LSI that integrates in a single
chip the signal processing functions required for compact
disk graphics (CD-G) decoding. The LC7872E accepts the
subcode R to W signals output by a CD-DSP chip such as
the Sanyo LC786X series, LC7862XE series or
LC7863XE series and performs de-interleaving, error
detection and correction, graphics instruction processing
and image processing.
Functions
Built-in RGB encoder allows a CD-G decoder to be
implemented in just two chips: the LC7872E and an
external 64-kword × 4-bit DRAM
Interpolation and protection for the CD subcode
synchronization signals as well as de-interleaving, error
detection and correction for the R to W signals.
Two crystal oscillator systems, one for NTSC and one
for PAL are provided and can be switched easily using
the control pin provided. The standard clock and all
required internal timings can be generated by
connecting a 14.31818 MHz crystal for NTSC and/or a
17.734476 MHz crystal for PAL.
The LC7872E performs CD graphics instruction
processing and drawing processing and controls the
image display.
Composition video 8-bit D/A converter output provided
Superimposition support
Microprocessor interface provided to support set
upgrades.
Define transparency support
Color bar output function
Features
A CD-G decoder can be implemented with just two
chips: a controller is not required.
Silicon gate CMOS structure for low power operation
Single 5 V power supply
64-pin QFP (QIP) package
Package Dimensions
