9. PCI Express Endpoint Connectivity

The 8-lane PCIe edge connector performs data transfers at the rate of 2.5 GT/s for a Gen1 application and 5.0 GT/s for a Gen2 application. The Virtex FPGA GTX MGTs are used for the multi-gigabit per second serial interfaces.

The ML605 board trace impedance on all PCIe lanes supports both Gen1 and Gen2 applications. The ML605 supports up to Gen1 x8 and Gen2 x4 as shipped with a -1 speed grade for the LX240T device.

Figure 1-11, page 32 is a diagram of the PCIe MGT bank 114 and 115 clocking.

Note: PCIe edge connector signal nomenclature is
from perspective of the system/motherboard.
