The BCM5703S 10/100/1000BASE-T Gigabit Ethernet media access
control and serializer/deserializer (SerDes) is a fully integrated interface
solution for high-performance network applications. The BCM5703S 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 SerDes
transceiver in a single device. The BCM5703S is fabricated in a low-
voltage 0.13-µm CMOS process, providing a low-power system
solution. By itself the BCM5703S provides a complete single-chip
Gigabit Ethernet NIC or LOM solution.
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 BCM5703S provides both PCI v2.2 and PCI-X v1.0 bus interfaces.
It also provides large on-chip buffer memory for stand-alone operation.
Dual, on-chip, high-performance processors enable custom frame
processing features, including TCP segmentation.
Along with complying with the IEEE 802.3z specification, several
enhancements, such as ultra-low jitter technology, have been added to
make designs even more robust.
