The Ethernet 100G MAC IP, compliant with the IEEE802.3/802.3ba standard, implements the full MAC layer and reconciliation sub-layer for 10/20/40/50/100G operation. The IP also supports industry standard 25/50G operations.
Configuration pins are available to dynamically set the IP to terminate and form MAC frames (NIC application) or to pass MAC frames to the application or the Ethernet line without modifications. In either application, the IP supports IEEE managed objects, IETF MIB-II and RMON. On the application side, the MAC implements a flexible FIFO interface that can be connected to a custom user application. On the Ethernet line side, the MAC implements a wide CGMII/XLGMII (100G/40G Medium Independent Interface) for a 10G operation.
The IP supports Energy Efficient Ethernet (EEE) signaling for power management as per defined by the IEEE 802.3az standard. The IP supports the IEEE 802.3br standard by providing two transmit and receive interfaces. The preemptable MAC interface is the low-priority interface where frames can be preempted. The express MAC interface is the high-priority interface where frames are sent over preemptable frames. Two traffic classes over the preemptable MAC interface support 802.1qav (Audio Video Bridging (AVB)) applications.
The 100G Ethernet MAC IP seamlessly interoperates with the 100G Ethernet PCS IP to deliver a complete solution for 100G Ethernet Systems.
