The BCM5703 is a fully integrated 10/100/1000B ASE-T Gigabit
Ethernet Media Access Control and Physical Layer Transceiver
solution for high performance network applications. The
BCM5703 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
BCM5703 is fabricated in a low-voltage, 0.13-um CMOS
process providing a low-power system solution. By itself the
BCM5703 provides a complete single-chip Gigabit Ethernet
NIC or LOM solution.
The BCM5703 includes a 10/100/1000-Mbps Ethernet MAC
with full/half-duplex capability at all speeds, and 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 BCM5703 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 gi ves installers
an instant visual indication if there are any issues with the wiring
plant supporting operation at the desired speed. 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 BCM5703
continually monitors various channel conditions. The optional
wire-speed capability allows the BCM5703 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.
