The
BCM5701
is a fully-integrated 10/100/1000BASE-T
Gigabit Ethernet Media Access Control and physical layer
transceiver solution for high-performance network
applications. The
BCM5701
is a highly integrated solution
combining triple-speed, IEEE 802.3 compliant media access
controller (MAC), PCI and PCI-X bus interfaces, on-chip
buffer memory, and integrated physical layer transceiver in a
single device. The
BCM5701
is fabricated in a low-voltage,
0.18 µm CMOS process, providing a low-power system solution.
By itself the
BCM5701
provides a complete, single-chip Gigabit
Ethernet NIC or LOM solution.
The
BCM5701
includes a 10/100/1000-Mbps Ethernet MAC
with full/half-duplex capability at all speeds, and a 10/100/1000
copper PHY. Support for the following 802.3 functions is
featured in the MAC: VLAN tagging, layer 2 priority encoding,
link aggregation, and full-duplex flow control.
The device provides both PCI v2.2 and PCI-X v1.0 bus
interfaces. The
BCM5701
provides a large on-chip buffer
memory for stand-alone operation. Dual on-chip, high-
performance processors enable custom frame processing
features, including TCP segmentation.
The transceiver is fully compatible with the IEEE 802.3 standard
for auto-negotiation of speed. Additionally, several Plug and Play
enhancements have been added to make the device even more
user friendly. A link quality indicator LED gives installers an

instant visual indication if there are any issues with the wiring
plant supporting operation at the desired speed. 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. The
BCM5701
continually monitors various channel conditions. The optional
wire speed capability allows the
BCM5701
to force auto-
negotiation to be automatically limited by the speed that the
channel can reliably support, rather than the performance of the
end equipment.
