GENERAL 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.
