So on we are using an NI 6583 (DDC B connector the 12x 73 pin LVDS connector) and we are hooking it up to a NI7971R FPGA board. Would anyone know if there is a way to get both a differential LVDS clock coming out (which seems the case with the DDC clock out or strobe pairs) but we need a differential clock going in as well. Can that be done with this configuration? Can you use one of the PFI pairs as a clock input on the FPGA?
