Semiconductor manufacturers are always looking for the best interconnect solution to characterize the high-speed transceivers found on their FPGAs, ASICs and ASSPs.  Typically, PCB-mount SMA connectors have been used to breakout the differential transmit and receive signals found in modern transceivers.  Below is a Xilinx Spartan-6 FPGA SP623 Characterization Kit which features a number of PCB-mount SMA connectors. This approach worked for decades. Transceiver counts per IC … [Read more...]
