BCM5720 Gigabit Ethernet: Energy Efficient Ethernet support, hardware support for IEEE 1588 timestamping, to connection for better system manageability.Designed for today's enterprise and data environments, Broadcom's NetXtreme 1G Ethernet controllers are the ideal solution for multi-core servers, delivering full -rate throughput on all ports. 2.1 1x Dual Port 1G LAN BCM5720 Ethernet Controller is a 13th generation 10 or 100 or 1000BASE-T and 10 or 100 or 1000BASE-X Ethernet LAN controller solution for high performance server and networking applications.The interface supports separate PCI functions for each LAN interface. The BCM5720 includes I or O Virtualization (IOV) functions such as 17 receive and 16 transmit queues, and 17 -X vectors with flexible vector-to-queue association.These IOV capabilities enable the BCM5720 to support NetQueue and VMQ technologiesIntegrated dual 10 or 100 or 1000BASE-T and dual 1000BASE-X or SGMII 1.25 Gbaud SerDes transceivers.Energy Efficient Ethernet (EEE) compliant with IEEE Std 802.3az 2010Dual 10 or 100 or 1000BASE-T full or half duplexDual 1000BASE-X or SGMII Full or Half DuplexAutomatic Crossoverx2 PCI v2.0 at 5 GT or s or 2.5 GT or sand -X capabilities - up to 17 -X vectorsI or O Virtualization (IOV) support for NetQueue and VMQ17 receive queues and 16 transmit queues17 -X vectors support interrupt to per queueFlexible -X vector for send or receive queue associationTLP Processing (TPH) ECN Compliant with PCI Base Specification v2.0Supports jumbo frames with payloads up to 9600 bytesVirtual LAN (VLAN) support - IEEE 802.1q VLAN tagging, IP, UDP checksum offloadSend Offload (), Segmentation Offload ()Hardware-Assisted Implementation of IEEE 1588 and IEEE 802.1AS Time SynchronizationIEEE 802.3x controlOn-chip temperature monitorPCI CLKREQ supportPower Management Offload (PM Offload)Serial Flash and EEPROM NVRAM supportFlash auto-configurationECC Error Detection and Correction on Internal SRAMMaterial: PCBcolour: greenPackage Contents:1 x Network Card1 x Driver-CD1 x Short Iron PieceOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
