SAA7120; SAA7121; Digital Video Encoder (ConDENC)
| Description |  |
|
The SAA7120; SAA7121 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.
