PCI Express Endpoint Connectivity
[
The 16-lane PCI Express edge connector CN1 performs data transfers at the rate of 2.5
giga-transfers per second (GT/s) for Gen1, 5.0 GT/s for Gen2, 8.0 GT/s for Gen3, and 16.0
GT/s for Gen4 applications. The PCIe transmit and receive signal datapaths have a
characteristic impedance of 85
Ω
±10%. The PCIe clock is routed as a 100
Ω
differential pair.
The FPGA GTY MGT connections for the 16-lane PCIe connector are listed in
