PCI bandwidth changes. Advanced interrupt ® Intel in Communications The Intel 82545GM Gigabit Ethernet Controller The Intel 82545GM integrates Intel’s fourthgeneration Gigabit MAC design with fully integrated, physical-layer circuitry to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, 802.3ab). For Ethernet on the backplane and fiber-optic applications, the Intel 82545GM’s integrated SerDes supports 1000BASE-X (802.3z). In addition, the controller provides a direct Peripheral Component Interconnect (PCI) 2.3 and PCI-X 1.0a compliant bus at clock frequencies up to 133MHz. moderation hardware manages interrupts generated by the 82545GM controller to further improve system efficiency. In addition, using hardware acceleration, the controller also offloads tasks from the host processor, such as TCP/UDP/IP checksum calculations and TCP segmentation. Applications The Intel 82545GM Gigabit Ethernet Controller is designed for use in the following applications: constrained systems such as rack-mounted The Intel 82545GM on-board SMBus port enables enhanced manageability and system health monitoring via the LAN: management packets can servers and high-density blade servers industry standards such as IPMI (Intelligent Platform Management Interface). In addition, ASF 1.0 (Alert Standard Format) circuitry provides alerting and remote-control capabilities with standardized interfaces.
