4.3.8 Tri-Speed Ethernet PHY
The SAMA5D3 series CM board is equipped with a MICREL PHY device (MICREL KSZ9021/31) operating at
10/100/1000 Mbps. The board supports the RGMII interface mode. The Ethernet interface consists of four pairs of low-
voltage differential pair signals designated from GRX± and GTx± plus control signals for link activity indicators. These
signals can be used to connect to a 10/100/1000 Base-T RJ45 connector integrated on the main board.
For more information about the Ethernet controller device, refer to the MICREL KSZ89021RN controller manufacturer's
datasheet.
