Intel® 82580EB/82580DB GbE Controller: DatasheetIntroductionThe Intel® 82580EB/82580DB Gigabit Ethernet 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 82580EB/DB supports PCI Express* (PCIe v2.0 (5Gbps and 2.5Gbps)).The device 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 possible system configuration is for blade servers. Here, the 82580EB/DB 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.ScopeThis document provides the external architecture (including device operation, pin descriptions, register definitions, etc.) for the 82580EB/DB.This document is a reference for software device driver developers, board designers, test engineers, and others who may need specific technical or programming information.Read the full Intel® 82580EB/82580DB GbE Controller datasheet.
