This section describes the standards that are supported by the AXI Ethernet Subsystem.
-
The Gigabit Media Independent Interface (GMII) is defined by the IEEE 802.3 specification; it can provide support for Ethernet operation at 10 Mbps, 100 Mbps, and 1 Gbps speeds.
- The Media Independent Interface (MII) is defined by the IEEE 802.3 specification; it can provide support for Ethernet operation at 10 Mbps and 100 Mbps speeds.
- 1000BASE–X Physical Coding Sublayer (PCS), Physical Medium Attachment (PMA), and RGMII operation, as defined in the IEEE 802.3-2008 standard.
- GMII to Serial-GMII (SGMII) bridge or SGMII to GMII bridge, as defined in the Serial-GMII specification (ENG-46158).
- Reduced Gigabit Media Independent Interface (RGMII), version 2.0.
- IEEE 802.1AS Supports clock master functionality, clock slave functionality, and the Best Master Clock Algorithm (BMCA).
- IEEE 802.1Qav Supports arbitration between different priority traffic and implements bandwidth policing.
These standards are implemented by the respective cores used in the AXI Ethernet Subsystem. For more details related to these, see the Tri-Mode Ethernet MAC LogiCORE IP Product Guide (PG051). and 1G/2.5G Ethernet PCS/PMA or SGMII LogiCORE IP Product Guide (PG047).
