Gigabit Ethernet Interface
The Stratix V GX development board incorporates a triple speed 10/100/1000 Base-T
Ethernet RGMII interface.
The implementation uses an auto-negotiating Marvell 88E1111 Ethernet PHY (U50)
with an RGMII interface to the FPGA (using Altera Triple-Speed Ethernet MegaCore
MAC function) and to a RJ-45 connector (J57) with internal magnetics that can be used
for driving copper lines with Ethernet traffic.
Figure 2–9 shows the RGMII interface between the FPGA and Marvell 88E1111 PHY.
