The ZCU111 board uses the TI DP83867IRPAP Ethernet RGMII PHY [Ref 20] (U37) for 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 Table: DP83867 PHY Connections to XCZU28DR RFSoC.
