The development board supports a 10/100/1000 BASE-T Ethernet connection using a Marvell 88E1111 PHY device and the Intel Triple-Speed Ethernet Megacore MAC function. The device is an auto-negotiating Ethernet PHY with an SGMII interface to the FPGA. The Intel® Arria® 10 GX FPGA device can communicate with the LVDS interfaces at up to 1.25 Gbps. The MAC function must be provided in the FPGA for typical networking applications. The Marvell 88E1111 PHY uses 2.5-V and 1.2-V power rails and requires a 25-MHz reference clock driven from a dedicated oscillator. It interfaces to an RJ-45 connector with internal magnetics that can be used for driving copper lines with Ethernet traffic.
