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 21] .
