Intel® 82583V Gigabit Ethernet Controllers

Low-Power, Small-Footprint, Dual-Port Gigabit Network Connectivity with Advanced Performance Features


      This Mini PCIe Gigabit Network card is single, compact, low power components that offer a fully-integrated Gigabit Ethernet Media Access Control and physical layer port. It is used of Intel high-performance chip NH82583V,and it is uses the PCI Express architecture and provides a Dual-Port implementation in a relatively small area so it can be used for server and any other personal computers. The Intel 82583L also enables a quick migration from custom interconnects to Ethernet.Each Controller provides MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab).
