BCM5701_05 Datasheet, PDF (2/2 Pages) Broadcom Corporation. – 10/100/1000BASE-T CONTROLLER WITH INTEGRATED TRANSCEIVER

BCM5701 OVERVIEW
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.
