Overview The LC78011E is a CMOS IC that integrates a digital RGB encoder and a synchronizing signal generation circuit on a single chip. A video CD or CD-G system can be formed using the LC78011E together with an MPEG video decoder or a CD-G decoder, respectively. Features • System structure — Each system (Video CD or CD-G system) formed with an additional chip: MPEG decoder or CD-G decoder chip. • Video outputs — 8-bit D/A converter outputs: 2 channels — The LC78011E supports the following two video signal output formats: Luminance signal (Y) and chroma signal (C) outputs Composite video signal (C • VIDEO) output (Only one D/A converter channel operates in this mode.) • System clock — External 4fsc clock NTSC mode: 14.31818 MHz PAL mode: 17.734475 MHz PAL-M mode: 14.30244596 MHz • External subcarrier input — An external fsc clock is input and used for subcarrier synchronization timing. • Video data input — The LC78011E supports the following four input formats: R, G, and B: 8 bits each Y, U, and V: 8 bits each Y and UV: 8 bits each (The UV input is a multiplexed input) R, G, and B: 4 bits each (In CD-G input support mode) • OSD input support — R, G, and B + BLK 4-bit inputs (color support) (BLK is an OSD display switching timing signal.) • External synchronizing signal input — Horizontal synchronizing signal, composite synchronizing signal, and composite blanking signal inputs: HSYNC, CSYNC, and BLANK. • Video signal formats — The LC78011E supports the NTSC, PAL, and PALM formats.
