10/100/1000 Mhz Tri-Speed Ethernet Phy - Xilinx ZCU111 User Manual

10/100/1000 MHz Tri-Speed Ethernet PHY

[Figure 2-1, callout 12]
The ZCU111 board uses the TI DP83867IRPAP Ethernet RGMII PHY
Ethernet communications at 10 Mb/s, 100 Mb/s, or 1000 Mb/s. The board supports RGMII
mode only. The PHY connection to a user-provided Ethernet cable is through a Wurth
7499111221A RJ-45 connector (P12) with built-in magnetics. The Ethernet connections from
XCZU28DR RFSoC U1 to the DP83867IRPAP PHY device at U37 are listed in
