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, on-chip buffer
memory, and an integrated SERDES transceiver in a single
device. The BCM5703S is fabricated in a low-voltage .13µ
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 device provides both PCI v2.2 and PCI-X v1.0 bus
interfaces. The BCM5703S 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 IEEE 802.3z specification, several enhancements,
such as ultra-low jitter technology, have been added to make
designs even more robust.
