3. Quick reference data
The SAF7167AHW is a mixed-mode designed IC containing a video data path, keying
control block, analog mixer, and a voltage output amplifier, capable of converting digital
video data to analog RGB video, and then mixing video and external analog RGB inputs.
The video data path contains a data re-formatter, YUV-to-RGB colour space matrix as well
as triple DACs for video data processing. An analog mixer performs multiplexing between
DAC outputs of the video path and external analog RGB inputs.
The final analog outputs are buffered with built-in voltage output amplifiers to provide the
direct driving capability for a 150
The operation of SAF7167AHW is controlled via the I
