# XAUI 10Gb Ethernet Interface

## Description

XAUI is a high-speed interconnect that has the ability to drive up to 20 inches of PCB trace on standard FR-4 material. Each XAUI interface comprises four self-timed 8b/10b encoded serial lanes each operating at 3.125 Gbits/s and thus is capable of transferring data at an aggregate rate of 10 Gbits/s. The Lattice Semiconductor XAUI 10Gb Ethernet Interface IP provides a solution for bridging between XAUI and 10-Gigabit Media Independent Interface (XGMII) devices. This IP core implements 10Gb Ethernet Extended Sublayer (XGXS) capabilities in soft logic that together with PCS and SERDES functions implemented in the FGPA provides a complete XAUI-to-XGMII solution.
