DESCRIPTION
2
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
