The BCM5721 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 BCM5721 is fabricated in a lowvoltage silicon process, providing an ultra-low power solution. By itself, the BCM5721 provides a complete single-chip Gigabit Ethernet NIC or LOM solution. The BCM5721 includes a 10/100/1000-Mbps Ethernet MAC with fullduplex 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 • Full-duplex flow control Broadcom’s remote cable management and diagnostics software can be used with the device to provide remote management of the cable and a first level of diagnostics and fault isolation. Target applications of the BCM5721: • Server PC NIC • Server PC LOM Software drivers available: • Windows NT®, 2000, XP, and 2003 • Linux® 2.2 and 2.4 • NetWare® • Solaris™ x86 • UNIX® The transceiver is fully compatible with the IEEE 802.3 standard for auto-negotiation of speed. Additionally, several Plug-and-Play enhancements are included to make the device even more user-friendly. A unique integrated cable analyzer feature allows a user to self-diagnose any issues with the network cabling that could affect the host machine. A link quality indicator LED and a GUI application give installers an instant visual indication of problems. This includes physical wiring defects or channel conditions, such as excessive cable length, return loss, crosstalk, echo, and noise.
