Hi,

The DVI signals are differential current fed signals. The DVI spec can be found at:

http://www.ddwg.org/lib/dvi_10.pdf

Starting at page 33 you'll find the electrical specification, too long to describe here. The standard states a current fed differential signalling, but using just a short cable and proper resistive loads/impedance matching it might be possible to achieve this even with a voltage output at Cyclone I/II ?? Or are there any other vendors that have FPGA's that can do DVI directly??

Regards,

Christian
