LC78011E
Digital RGB Encoder IC for Video CD and CD-G
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 PAL-
M formats.
