SAF7167AHW: YUV-to-RGB digital-to-analog converter ARCHIVED

Overview

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 Ω load. See the overall block diagram.

The operation of SAF7167AHW is controlled via the I²C-bus.
