The BCM5751 is a fully integrated 10/100/1000BASE-T
Gigabit Ethernet media access control and physical layer
transceiver solution for high-performance network applications.
The BCM5751 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. It is fabricated in a low-voltage silicon
process, providing an ultra-low power solution. By itself the
BCM5751 provides a complete single-chip Gigabit Ethernet
NIC or LOM solution.
The BCM5751 includes a 10/100/1000-Mbps Ethernet MAC
with full/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 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
an end 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.
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 BCM5751:
•Desktop PC NIC
•Desktop PC LOM
Software drivers available:
•Windows98, NT, 2000, XP
•Linux2.2, 2.4
