Ethernet Ports (J4 and J9)

The AWR2E44PEVM supports two RGMII Ethernet ports to provide the connection to the network. The J4 connector provides access over a MATEnet port (9-2304372-9 connector) via a DP83TG720SWRNDR-Q1 PHY. The J9 port provides access over an RJ45 port via a DP83867ERGZR PHY. By default, the RGMII interfaces are connected to the J9 port only. To access the RGMII interface, over the J4 connector several resistors must be populated. For more details please see ECOs to Enable the DP83TG720SWRNDR-Q1 PHY and refer to the Schematic, BOM, and Assembly and Database and Layout sections.

This RGMII interface is intended to operate primarily as a 1000Mbps ECU interface and can also be used as an Instrumentation Interface.

The RGMII interface supports following features:

  • Full Duplex 10/100/1000Mbps wire rate Interface to Ethernet PHY over RGMII, parallel interface
  • MDIO Clause 22 and 45 PHY management interface
  • IEEE 1588 Synchronous Ethernet support

The Ethernet port is interfaced to the AWR2E44P through the Ethernet PHY and is used to stream the captured data over the network to the host PC.

Figure 2-6 shows the Ethernet RJ45 Mag-Jack connector, and Table 2-3 provides the connector pin details.
