Detailed Description
R
21. 10/100/1000 Tri-Speed Ethernet PHY
The board contains a Marvell Alaska PHY device (88E1111) operating at
10/100/1000 Mb/s. The board supports MII, GMII, RGMII, and SGMII interface modes
with the FPGA. The PHY is connected to a Halo HFJ11-1G01E RJ-45 connector with built-in
magnetics. The PHY is configured to default at power-on or reset to the settings shown in
Table 1-15 . These settings can be overwritten via software. All modes are selectable by the
jumpers as shown in Table 1-15 .
