Description

The SAA7167 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 of SAA7167 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 of SAA7167 are buffered with built-in voltage output amplifiers to provide the direct driving capability for a 150 load. Figure 1 shows the overall block diagram.

The operation of SAA7167 is controlled via the I2C-bus.
