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

, which include 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.
