The BCM5705M is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high-performance network applications. The BCM5705M combines a
triple-speed, IEEE 802.3-compliant media access controller (MAC), PCI
bus interface, on-chip buffer memory, and integrated physical layer
transceiver in a single device. It is fabricated in a low-voltage 0.13-mm
CMOS process, providing an ultra-low power solution. By itself the
BCM5705M provides a complete single-chip Gigabit Ethernet NIC or
LOM solution.
The BCM5705M 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, link aggregation, and full-duplex flow control.
The device provides three host interfaces for mobile applications: PCI
v2.2, MiniPCI, and Cardbus. Also integrated is an on-chip memory
buffer for stand-alone operation. An embedded high-performance
processor enables 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 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 be affecting the
host machine. A link quality indicator LED and a GUI application give
installers an instant visual indication of a problem, 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 BCM5705M is also optimized to extend battery life. Several power
management enhancements are included that allow minimum usage of
battery power.
