I will use an ADV7842 in a new design with a DVI-I port and I have some questions.
The chip will receive a RGB 800*600 @50Hz analog or digital stream via the DVI-I port. A microprocessor will configure the chip and will select the video stream. The output format will be YCbCr 4:2:2.
1) There's only one DDC-SDA pin on a DVI-I connector, which DDC pin should I choose on the ADV (VGA or DDCA) ?
2) I've read that this chip can do colorspace conversion from RGB to YCbCr 4:2:2 without problem, is this exact ?
3) Is it possible to receive a 800*600@50Hz digital stream (not a vesa standard) ?
