The BCM5761 combines a triple-speed, IEEE 802.3™compliant media access controller (MAC), PCI Express bus interface, on-chip buffer memory, and integrated physical layer transceiver in a single device. The BCM5761 is fabricated in a low-voltage silicon process, providing an ultralow power solution. By itself, the BCM5761 provides a complete single-chip GbE NIC or LOM solution. The BCM5761 includes a 10/100/1000 Mbps Ethernet MAC with fullduplex and half-duplex capability at all speeds. Support for the following IEEE 802.3 functions is featured in the MAC: VLAN tagging, Layer 2 priority encoding, and full-duplex flow control. The BCM5761 controller offers IPsec task offload capabilities compliant with Microsoft v2 logo requirements. This capability enables IT professionals to deploy IPsec technology on their existing network with no performance penalty, while maintaining low CPU utilization and high network capacity by offloading all the cryptographic processing to the hardware. In-line offload architecture in the BCM5761 enables network security at an extremely low cost. With network topologies becoming more complex with increased mobility and remote workers, virus and worm security threats are now more sophisticated. IPsec protocols operate at the network layer and enable end-to-end authentication and encryption between clients and servers, allowing efficient network segmentation and isolation. The BCM5761 integrates an on-chip Application Processing Engine (APE) with its runtime memory providing a complete Web servicesbased management functionality via Broadcom TruManage technology. This single-chip highly integrated product offers a scalable and centralized architecture, which, combined with a highly optimized firmware and software, enables low-power, secure, fault-tolerant, and cost-effective implementation. Target applications of the BCM5761: • Desktop and mobile PC LOM Software drivers available: • Windows® 2000, Windows NT®, Windows XP®, and Windows Vista® • Linux® 2.2, 2.4, and 2.6 Broadcom®, the pulse logo, Connecting everything®, the Connecting everything logo, NetXtreme®, the NetXtreme logo, and TruManage™ are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
