GENERAL DESCRIPTION
The SAA7124; SAA7125 encodes digital YUV video data
to an NTSC or PAL CVBS plus RGB or alternatively to
S-Video and CVBS output.
Optionally, the YUV to RGB dematrix can be by-passed
providing the digital-to-analog converted Cb, Y, Cr signals
instead of RGB.
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).
