Ethernet CTLR Single Chip

The Intel 82580EB 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 82580EB/DB supports PCI Express (PCIe v2.0 (5Gbps and 2.5Gbps)).

• PCIe v2.0 (5Gbps and 2.5Gbps) x4/x2/x1; called PCIe in this document.
• MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab)
• Serializer-Deserializer (SERDES) to support 1000Base-SX/ LX (optical fiber)
• Serializer-Deserializer (SERDES) to support 1000BASE-KX and 1000BASE-BX for Gigabit backplane applications
• SGMII interface for SFP/external PHY connections
• NC-SI or SMBus for Manageability connection to MC
• IEEE 1149.6 JTAG
