10/100/1000 Ethernet
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 Stratix IV GX device can communicate with the LVDS interfaces at up to 1.6 Gbps,
which is faster than 1.25 Gbps for SGMII. The MAC function must be provided in the
FPGA for typical networking applications. The Marvell 88E1111 PHY uses 2.5-V and
1.1-V power rails and requires a 25-MHz reference clock driven from a dedicated
oscillator. It interfaces to an RJ-45 with internal magnetics that can be used for driving
copper lines with Ethernet traffic.
