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,

0.18um 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 , se v eral 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.
