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, 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 BCM5705 continually
monitors various channel conditions. The optional wirespeed 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.
