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.
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
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
