This post is going to be about Breakout board PCB for FMC Connector which are widely used on Xilinx High End FPGA board. LPC Low pinout connections do not have any GTY or GTH or GTX or MGT connections they have only differential normal SerDes connections ANSI/VITA 57.1 compliant YouTube  Schematic  Schematic has only 4 LPC rows connected directly to Top layer and board layer connector. 1.27 mm Header route out all connections including GND pins all the Signals are routed in Differential connection  PCB Signal Rows in FMC LPC vs. HPC Connector pins Difference Row LPC (160 Pins) HPC (400 Pins) Function A ❌ No ✅ Yes Power, control, & reference clocks B ❌ No ✅ Yes Additional I/O and clocks C ✅ Yes ✅ Yes Single-ended I/O & differential pairs D ✅ Yes ✅ Yes More I/O & differential pairs E ❌ No ✅ Yes Additional differential pairs (DP0-9) F ❌ No ✅ Yes More differential pairs (DP10-17) G ✅ Yes ✅ Yes Primary differential pairs & clocks H ✅ Yes ✅ Yes More primary...
