Intel 82546/82580 Gigabit Ethernet Controllers

Intel's 82546/82580 Gigabit Ethernet Controllers are a single, compact components that support integrated gigabit Ethernet media access control (MAC), physical layer (PHY) ports and four SGMII/SerDes ports that can be connected to an external PHY. The 82580 supports PCI Express (PCIe v2.0 (5Gbps and 2.5Gbps)) and enables two-port or four port 1000BASE-T implementations using integrated PHY’s. The 82546 integrates a gigabit MAC and PHY to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab). The controller is capable of transmitting and receiving two channels of data at rates of 1000Mbps, 100Mbps, or 10Mbps.

Intel's 82546 Dual Port Gigabit Ethernet Controller is a single, compact component with two full integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. It enables dual port Gigabit Ethernet implementations in a very small area and can be used for desktop and workstation PC network designs as well as backplane applications with critical space constraints. The 82546 integrates Intel’s fourth generation gigabit MAC and PHY to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab). The controller is capable of transmitting and receiving two channels of data at rates of 1000Mbps, 100Mbps, or 10Mbps. In addition, it provides a 64-bit wide direct Peripheral Component Interconnect (PCI) 2.3 and PCI-X 1.0a compliant interface capable of operating at frequencies up to 133MHz.

Intel's 82580 GbE Controller is a single, compact, low power component that supports quad and dual port gigabit Ethernet designs. The device offers four fully-integrated gigabit Ethernet media access control (MAC), physical layer (PHY) ports and four SGMII/SerDes ports that can be connected to an external PHY. The 82580 supports PCI Express (PCIe v2.0 (5Gbps and 2.5Gbps)). It enables two-port or four port 1000BASE-T implementations using integrated PHY’s. It can be used for server system configurations such as rack mounted or pedestal servers, in an add-on NIC or LAN on Motherboard (LOM) design. Another system configuration is for blade servers, where the 82580 can support up to 4 SerDes ports as LOM or mezzanine card. It can also be used in embedded applications such as switch add-on cards and network appliances.
