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 4:2:2multiplexed formats, for example MPEG decoded data. It includes a sync/clock generator and on-chip DACs.
