Hello All,
I’m urgently looking for approx. 6 or 8-inch flexible extension cable to extend the FMC HPC (High Pin Count) interface on a Xilinx VC707 FPGA board. The FMC connector is a Samtec SEAM/SEAF series, VITA 57.1 compliant, with a 10x40 (400-pin) array, supporting up to 80 differential LVDS pairs.
This extension needs to be a high-speed ribbon or twinax cable assembly, not a rigid extender board, and must preserve signal integrity for high-speed differential LVDS signaling. The preferred configuration would be QSH (socket) to QTH (plug) or another compatible mating pair for FMC headers.
If you’re aware of a part available through Digi-Key/other, or if a custom assembly is required, I’d appreciate any recommendations. This is for time-sensitive for prototyping.
Thank you in advance for your help and please let me know if you need more info.
