2. Features

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
