7.12.3 Ethernet Switch (RGMII/RMII/MII) Peripheral

Note:

AWR2944LC and AWR2E44LC do not support Ethernet Switch (RGMII/RMII/MII) Peripheral.

The device integrates a two port Ethernet with one external RGMII/RMII/MII port and another port servicing the Main Sub-System (MSS). This interface is intended to operate primarily as a 1000Mbps ECU interface. It can also be used as an instrumentation interface.

  • Full Duplex 10/100/1000Mbps wire rate interface to Ethernet PHY
    • AWR2944P: over RGMII, or RMII, or MII parallel interface
    • AWR2E44P: over RGMII, or RMII parallel interface
  • Full Duplex 10/100Mbps wire rate interface to Ethernet PHY on the ECO variant
    • AWR2944-ECO: over RGMII, or RMII, or MII parallel interface
    • AWR2E44-ECO: over RGMII, or RMII parallel interface
  • MDIO Clause 22 and 45 PHY management interface
  • IEEE 1588 Synchronous Ethernet support
  • AWR synchronous trigger output allowing Ethernet to trigger radar frames
