The
BCM5705
is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet Media Access Control and Physical Layer Transceiver solution
for high-performance network applications. The
BCM5705
combines a
triple-speed, IEEE 802.3 compliant media access controller (MAC), a
PCI bus interface, an on-chip buffer memory, and an integrated physical
layer transceiver in a single device. The
BCM5705
is fabricated in a low-
voltage 0.13µ CMOS process, providing an ultra-low power solution. By
itself, the
BCM5705
provides a complete single-chip Gigabit Ethernet
NIC or LOM solution.
The
BCM5705
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
•
Full-duplex flow control
The device provides a PCI v2.2 bus interface and integrated on-chip
buffer memory for a 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 a user to self-
diagnose any issues with the network cabling that could affect the host
machine. A link quality indicator LED and a GUI application give
installers an instant visual indication of problems. 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
BCM5705
continually monitors various channel
conditions. The optional wire-speed capability allows the
BCM5705
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.
Target Applications of the BCM5705
