The PS-side Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mb/s Ethernet interface (see This Figure), which connects to a TI DP83867IRPAP Ethernet RGMII PHY before being routed to an RJ45 Ethernet connector. The RGMII Ethernet PHY is boot strapped to PHY address 5'b01100 (0x0C) and Auto Negotiation is set to Enable. The communication with the device is described in the DP83867 RGMII PHY data sheet [Ref 20].
