10/100/1000BASE-T Ethernet Controller with Integrated Transceiver
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 highperformance processors enable custom frame processing features, including TCP segmentation.
