On-board Ethernet PHY (Micrel KSZ9031RNX) provides interface signals required to implement the 10/100/1000 Mbps Ethernet port. The transceiver is connected to the Gigabit Ethernet Controller (GEM) through RGMII interface on MIO bank 1, pins PS_MIO[16:27]. For further details (eg: connection and selection of the magnetics), please refer to the Micrel KSZ9031RNX datasheet. The following table describes the interface signals:
| Pin name | Conn. pin | Function | Notes |
|---|---|---|---|
| ETH_TXRX0_P | J1.105 | Media Dependent Interface[0], positive pin | - |
| ETH_TXRX0_M | J1.103 | Media Dependent Interface[0], negative pin | - |
| ETH_TXRX1_P | J1.99 | Media Dependent Interface[1], positive pin | - |
| ETH_TXRX1_M | J1.97 | Media Dependent Interface[1], negative pin | - |
| ETH_TXRX2_P | J1.102 | Media Dependent Interface[2], positive pin | - |
| ETH_TXRX2_M | J1.100 | Media Dependent Interface[2], negative pin | - |
| ETH_TXRX3_P | J1.96 | Media Dependent Interface[3], positive pin | - |
| ETH_TXRX3_M | J1.94 | Media Dependent Interface[3], negative pin | - |
| ETH_MDIO | J1.87 | Management Data Input/Output | - |
