4.6 Ethernet Interface

4.6.1 RGMII
The AM263x Control Card uses one port of RGMII signals to be connected to a 48pin ethernet PHY
(DP83869HMRGZT). The PHY is configured to advertise 1-Gb operation. The ethernet data signals of the PHY
are terminated to an RJ45 connector. The RJ45 connector is used on the board for Ethernet 10/100/1000 Mbps
connectivity with integrated magnetic and LEDs for link and activity indication.
