Ethernet
A Dual Ethernet RJ45 interface is provided on the board front panel, and is connected to the FPGA.
This interface can operate in either 100Mbit or Gbit mode, and can be used for standard networking.
Two external PHY devices, (
Micrel KSZ9031RNX
) are implemented on the board.
These PHY devices interface to the FPGA using the RGMII interface standard.

Ethernet RGMII to FPGA interface (1 of 2 shown)
Each interface has a separate MDIO interface connection to the FPGA.
The interface signal to FPGA pin correspondence is listed in Table 4 and Table 5 .
