WG82574IT

IntroductionThe 82574 family (82574L and 82574IT) are single, compact, low power components that offer a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) port. The 82574 uses the PCI Express* (PCIe*) architecture and provides a single-port implementation in a relatively small area so it can be used for server and client configurations as a LAN on Motherboard (LOM) design. The 82574 family can also be used in embedded applications such as switch add-on cards and network appliances.External interfaces provided on the 82574:• PCIe Rev. 1.1 (2.5 GHz) x1• MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab)• NC-SI or SMBus connection to a Manageability Controller (MC)• IEEE 1149.1 JTAG (note that BSDL testing is NOTsupported)Additional product details:• 9 mm x 9 mm 64-pin QFN package• Support for PCI 3.0 Vital Product Data (VPD)• IPMI MC pass through; multi-drop NC-SI• TimeSync offload compliant with 802.1as specification
