The BCM5721 is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high-performance network applications. 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.
