The BCM5703 is a fully integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high performance network applications. The BCM5703 is a highly
integrated solution combining a triple-speed, IEEE 802.3 compliant
media access controller (MAC), PCI and PCI-X bus interfaces, an on-
chip buffer memory, and an integrated physical layer transceiver in a
single device. The BCM5703 is fabricated in a low-voltage, 0.13-µm
CMOS process providing a low-power system solution. 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 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
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 gives installers an instant visual
indication of 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 BCM5703 continually monitors various channel conditions. The
optional wirespeed capability allows the BCM5703 to force auto-
negotiation to be automatically limited by the speed that the channel can
reliably support (rather than by the performance of the end equipment).
