10/100/1000 Tri-Speed Ethernet PHY

[Figure
The VC707 board utilizes the Marvell Alaska PHY device (88E1111) U50 for Ethernet
communications at 10, 100, or 1000 Mb/s. The board supports SGMII mode only. The PHY
connection to a user-provided Ethernet cable is through a Halo HFJ11-1G01E RJ-45
connector (P4) with built-in magnetics.
On power-up, or on reset, the PHY is configured to operate in SGMII mode with PHY
address 0b00111 using the settings shown in
by software commands passed over the MDIO interface.
