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 802.3compliant 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 lowvoltage 0.13-m 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.
