10/100/1000 Mb/s Tri-Speed Ethernet PHY

[Figure 1-2, callout 17]
The KCU105 evaluation board uses the Marvell Alaska PHY device (M88E1111) at U58 for
Ethernet communications at 10 Mb/s, 100 Mb/s, or 1000 Mb/s. The board supports SGMII
mode only. The PHY connection to a user-provided Ethernet cable is through RJ-45
connector P3, a Halo HFJ11-1G01E-L12RL with built-in magnetics and status LEDs.
