A Marvell 88E1111 PHY device is used for 10/100/1000 BASE-T Ethernet connection.
The device is an auto-negotiating Ethernet PHY with an SGMII interface to the FPGA.
The MAC function must be provided in the FPGA for typical networking applications
such the Altera Triple Speed Ethernet MegaCore design. 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. The device interfaces to a Halo Electronics HFJ11-1G02E model
RJ45 with internal magnetics that can be used for driving copper lines with Ethernet
traffic.
By default, the GXB_RX1 and GXB_TX1 channels of the FPGA are connected to the
Ethernet PHY as shown in
Figure 2–6
