CMOS IC
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
鈥?System structure
鈥?Each system (Video CD or CD-G system) formed
with an additional chip: MPEG decoder or CD-G
decoder chip.
鈥?Video outputs
鈥?8-bit D/A converter outputs: 2 channels
鈥?The LC78011E supports the following two video
signal output formats:
Luminance signal (Y) and chroma signal (C) outputs
Composite video signal (C 鈥?VIDEO) output (Only
one D/A converter channel operates in this mode.)
鈥?System clock
鈥?External 4fsc clock
NTSC mode: 14.31818 MHz
PAL mode:
17.734475 MHz
PAL-M mode: 14.30244596 MHz
鈥?External subcarrier input
鈥?An external fsc clock is input and used for subcarrier
synchronization timing.
鈥?Video data input
鈥?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)
鈥?OSD input support
鈥?R, G, and B + BLK 4-bit inputs (color support)
(BLK is an OSD display switching timing signal.)
鈥?External synchronizing signal input
鈥?Horizontal synchronizing signal, composite
synchronizing signal, and composite blanking signal
inputs: HSYNC, CSYNC, and BLANK.
鈥?Video signal formats
鈥?The LC78011E supports the NTSC, PAL, and PAL-
M formats.
