Intel® 82546GB Dual Port Gigabit Ethernet Controller: Datasheet


The Intel® 82546GB 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. The Intel® 82546GB 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 Intel® 82546GB 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 1000 Mbps, 100 Mbps, or 10 Mbps. 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 133 MHz. The 82546GB also delivers a dual port PCI-X solution without added bridge latency.

The Intel® 82546GB on-board System Management Bus (SMB) port enables network manageability implementations required by information technology personnel for remote control and alerting through the LAN. Using the SMB, management packets can be routed to or from a management processor. The SMB port enables industry standards, such as Intelligent Platform Management Interface (IPMI) and Alert Standard Format (ASF), to be implemented using the 82546GB. In addition, on chip ASF 1.0 circuitry provides alerting and remote control capabilities with standardized interfaces.
