Ethernet MAC, 10 Gigabit (MorethanIP)

支持器件系列

• Virtex-5 LX
• Virtex-5 LXT
• Virtex-5 SXT

The 10 Gigabit Ethernet MAC Core is designed to comply with the IEEE802.3ae specification and meets the requirements for both WAN / MAN and LAN connectivity. The version 2 of the core can be used in either NIC (Network Interface Card) or ethernet switching applications. A set of configuration pins is available to dynamically set the core to terminate and form MAC frames (NIC application) or to pass MAC frames without modification to the user application or to the ethernet line (switching application). When used in NIC or switching applications, the core provides support for IEEE managed objects, IETF MIB-II and RMON for management applications (e.g. SNMP).

关键特性

• Full MAC layer and reconciliation sub-layer implementation compliant with IEEE802.3ae specification
• Passed UNH MAC, flow-Control, reconciliation and inter- operability tests
• Can be dynamically configured for NIC (Network Interface Card) applications or switching / bridging applications
• On ethernet line side, can be configured for either a XGMII or XAUI in Xilinx Virtex™-5 LXT FPGA
• Dynamic inter packet gap (IPG) calculation for WAN applications
• Deficit Idle Counter (DIC) for optimized performance with minimum IPG for LAN applications
• Simple 64-Bit client FIFO interface
