Got 3 minutes to watch Samtec’s 28Gbps FireFly Micro Flyover Cable Assemblies in action? Of course you do

Samtec recently posted a 3-minute video demonstrating its FireFly Micro Flyover Cable Assembly (the Twinax copper version) operating at 28Gbps per channel, error-free, over a total of 36 inches of cable. That one sentence describes the FireFly system’s advantage; it can carry high-speed data over longer distances using less power with no bit errors. That’s all in the video including this lovely, open eye diagram from the Xilinx LogiCORE IBERT IP core and software.

The demo uses a Xilinx VCU118 Eval Kit based on a Virtex UltraScale+ XCVU9P FPGA. Four SerDes transceivers on the FPGA operate at 28Gbps in this demo and directly drive the FireFly Twinax cables and received the looped-back data on a SamTec FireFly connector located adjacent to the UltraScale+ FPGA on the VCU118 Eval Kit. (The maximum transfer rate for the Virtex UltraScale+ GTY transceivers is 32.75Gbps and the Virtex UltraScale+ XCVU9P FPGA has 120 of those transceivers.)

 

Here’s the new Samtec video:
