2 GENERAL DESCRIPTION
The SAA7120H; SAA7121H encodes digital YUV video
data to an NTSC or 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 DACs.
