GENERAL DESCRIPTION
The SAA7185 encodes digital YUV video data to an
NTSC, PAL CVBS or S-Video signal.
The circuit accepts CCIR compatible YUV data with
720 active pixels per line in 4 : 2 : 2 multiplexed formats,
for example MPEG decoded data. It includes a sync/clock
generator and on-chip Digital-to-Analog Converters
(DACs).
The circuit is compatible to the DIG-TV2 chip family.
