• Manufacturer Part Number: bcm5761
• Description: Bcm5761 - 10/100/1000base-t Ethernet Controller With Integrated Security And Trumanage Technology
• Manufacturer: Broadcom Corp.

The BCM5761 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 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 full-
duplex and half-duplex capability at all speeds. Support for the following
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, 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.
With in-line offload architecture, the BCM5761 controller enables

network security at an extremely low cost. With network topologies
becoming more complex with increased mobility and remote workers,
security threats are now more sophisticated with viruses and worms.
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 services-
based management functionality via Broadcom’s TruManage
technology. The 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.
