X2 Pci Express Dual-port Gigabit Ethernet Controller

  The BCM5718 is a twelfth-generation 10/100/1000BASE-T Ethernet LAN controller solution suitable for high-performance server applications. The BCM5718 combines dual triple-speed IEEE 802.3 compliant Media Access Controllers (MACs) with dual 1000BASE-X/ SGMII SerDes Transceivers or dual 10/100/1000 Ethernet Transceivers (PHYs), selectable individually per port, a Network Controller Sideband Interface (NC-SI) and on-chip Memory Buffer in a single device. The device provides a PCI Express v2.0-compliant host Interface which can operate at 5GTs at x1 link width or at 2.5GT/s at x2 link width. The PCI Express supports MSI and MSI-X capabilities and Function Level Reset (FLR). The host Interface supports a separate PCI Express function for each LAN Interface The BCM5718 includes I/O Virtualization (IOV) features such as 17 receive and 16 transmit queues, 17 MSI-X vectors with flexible vector-to-queue association. These IOV features enable the BCM5718 to support the VMWare? NetQueue and Microsoft ? VMQ technologies. The BCM5718 is fabricated in a low-voltage 65 nm CMOS process, and integrates an efficient switching Voltage Regulator controller for core power supplies. Advanced Power Management features built into the BCM5718 enable minimizing the power consumption of the network controller subsystem by lowering the controller's power consumption under lighter network traffic without compromising performance. The BCM5718 implements Energy Efficient Ethernet (EEE) compliant to the IEEE Draft P802.3az?/D1.21 amendment to IEEE Std 802.3-2008, which further reduces the power consumption with idle 100Mbit or 1Gbit GPHY links. These features provide a low system power consumption Ethernet network Interface controller solution.
