GENERAL DESCRIPTION
The SAA7184 and SAA7185B digital video encoders 2
(DENC2-M6) encode 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. The device includes a
sync/clock generator and on-chip Digital-to-Analog
Converters (DACs).
The circuit is compatible to the DIG-TV2 chip family.
