VCU110 Evaluation Board Features
PCI Express Endpoint Connectivity
[
, callout 16]
The 4-lane PCI Express cable connector J136 performs data transfers at the rate of 2.5 GT/s
for Gen1 applications, 5.0 GT/s for Gen2 applications and 8.0 GT/s for Gen3 applications. The
PCIe transmit and receive signal data paths have a characteristic impedance of 85
Ω
±10%.
The PCIe clock is routed as a 100
Ω
differential pair.
The PCIe clock is input from the J136 PCIe cable connector and is AC coupled to FPGA U1
REFCLK0 pins of GTH Quad 233.
The PCIe J136 connection to FPGA U1 GTH Quad 233 is detailed in
.

LogiCORE IP UltraScale
FPGAs Gen3 Integrated Block for PCI Express v1.0 Product Guide for Vivado Design Suite
. Additional information about the PCI Express standard is available
