Part 4.6: Gigabit Ethernet Interface
The FPGA development board provides users with network
communication services through the Realtek RTL8211EG Ethernet PHY chip.
The RTL8211EG chip supports 10/100/1000 Mbps network transmission rate
and communicates with the FPGA through the GMII interface. RTL8211EG
supports MDI/MDX adaptive, various speed adaptations, Master/Slave
adaptation, and support for MDIO bus for PHY register management.
The RTL8211EG will detect the level status of some specific IOs to
determine their working mode after powered on. Table 4-6-1 describes the
default setup information after the GPHY chip is powered on.
