BCM5721 fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control physical layer transceiver solution high-performance network applications. BCM5721 combines triple-speed, IEEE 802.3 compliant media access controller (MAC), Express interface, on-chip buffer memory, integrated physical layer transceiver single device. BCM5721 fabricated lowvoltage silicon process, providing ultra-low power solution. itself, BCM5721 provides complete single-chip Gigabit Ethernet solution. BCM5721 includes 10/100/1000-Mbps Ethernet with fullduplex half-duplex capability speeds. Support following 802.3 functions featured MAC: VLAN tagging Layer priority encoding Full-duplex flow control transceiver fully compatible with IEEE 802.3 standard auto-negotiation speed. Additionally, several Plug-and-Play enhancements included make device even more user-friendly. unique integrated cable analyzer feature allows user self-diagnose issues with network cabling that could affect host machine. link quality indicator application give installers instant visual indication problems. This includes physical wiring defects channel conditions, such excessive cable length, return loss, crosstalk, echo, noise.
Broadcom's remote cable management diagnostics software used with device provide remote management cable first level diagnostics fault isolation. Target applications BCM5721: Server Server Software drivers available: Windows NT®, 2000, 2003 Linux® NetWare® Solarisx86 UNIX
