Intel 82574 Gigabit Ethernet PHYs

Intel's 82574 Gigabit Ethernet PHYs are single, compact, low power components that offer a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) port. The 82574L 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.
