Check device status and availability before design in!
Please check with your nearest sales or distributor office status and availability of devices listed on this page.
| Description |  |
|
The SAA7185 encodes digital YUV video data to an
NTSC, 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 Digital-to-Analog Converters
(DACs).
The circuit is compatible to the DIG-TV2 chip family.
