The Intel® 82546EB Dual Port Gigabit Ethernet Controller is a single, compact component with two full Gigabit Ethernet MAC and PHY layer functions. Packaged in a 21x21 mm PBGA, the Intel 82546EB Dual Port Gigabit Ethernet controller provides dual port functionality without additional board space requirements for the component and enables a dual port Gigabit Ethernet implementation in a very small area.
The Intel 82546EB integrates Intel%27s fourth generation Gigabit MAC design with fully integrated, physical-layer circuitry to provide two standard IEEE 802.3 Ethernet interfaces for 1000Base-T, 100Base-TX, and 10Base-T applications (802.3, 802.3u, 802.3ab). The controller is capable of transmitting and receiving two channels of data at 1000 Mb/s, 100 Mb/s, or 10 Mb/s data rates. For fiber optic applications, the Intel 82546EB%27s two integrated SERDES support 1000BASE-SX and 1000BASE-LX (802.3z). In addition, the controller provides a single, direct Peripheral Component Interconnect (PCI) 2.2 and PCI-X 1.0a compliant bus that operates as a single multi-function device on the bus at clock frequencies up to 133 MHz.
The Intel 82546EB%27s on-board SMBus port enables enhanced manageability and system health monitoring via the LAN. With SMBus, management packets can be routed to or from a management processor. The SMBus port enables industry standards such as IPMI (Intelligent Platform Management Interface) to be implemented with the Intel 82546EB. In addition, ASF 1.0 (Alert Standard Format) standard circuitry provides alerting and remote control capabilities with standardized interfaces.
