DESCRIPTION
GENERAL DESCRIPTION
The SAA7182A; SAA7183A encodes digital YUV video
data to an NTSC, PAL, SECAM CVBS or S-Video signal
and also RGB.
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).
The circuit is compatible to the DIG-TV2 chip family.
PACKAGE
This applies to SAA7183A only. The device is protected
