GENERAL DESCRIPTION
The SAA7182; SAA7183 encodes digital YUV video data
to an NTSC, PAL, SECAM CVBS or S-Video signal and
also RGB.
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.
