Part Number: SD387EVK
I am trying to drive the sma coaxial inputs of the evaluation card directly from an SDI output in our custom design from an Altera FPGA. The output originates at the FPGA, and goes thru a high speed interconnect to a pair of pads on an XMC adapter card. When attempting to use 2 coaxial cables to make the connections out of the adapter card to the 2 eval card inputs (6" run), it looks like we're charging capacitance in each coax line causing my eye diagram to not be present. Would a matched wire pair set like CAT 5E or CAT 6 cable be better than coaxial cables soldered on to the XMC adapter (we would have to pull the SMA connectors off of the eval card to solder the matched pair wire set). The coaxes we tried were Telex 405 from Times Microwave. Note our video is 1.485 Gbps SMPTE 292 format.
