BCM5761E

Description

The BCM5761E is a fully integrated 10/100/1000BASE-T Gigabit Ethernet (GbE) media access control and physical layer transceiver solution for high-performance network applications. The BCM5761E 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 BCM5761E is fabricated in a low-voltage silicon process, providing an ultralow power solution. By itself, the BCM5761E provides a complete single-chip GbE LOM solution.

The BCM5761E includes a 10/100/1000-Mbps Ethernet MAC with full-duplex and half-duplex capability at all speeds. BCM5761E support for the following 802.3 functions is featured in the MAC-VLAN tagging, Layer 2 priority encoding, and full-duplex flow control. The BCM5761E controller offers IPsec task offload capabilities compliant with Microsoft v2 logo requirements, which enables IT professionals to deploy IPsec technology on their existing network with no performance penalty and while maintaining low CPU utilization and high network capacity by offloading all the cryptographic processing to the hardware.
