10 Gigabit Attachment Unit Interface (XAUI / ˈzaʊi / ZOW-ee) is a standard for extending the XGMII (10 Gigabit Media Independent Interface) between the MAC and PHY layer of 10 Gigabit Ethernet (10GbE) defined in Clause 47 of the IEEE 802.3 standard.

XAUI, the 10 Gigabit Attachment Unit Interface, is a technical innovation that dramatically improves and simplifies the routing of electrical interconnections. Developed by the IEEE 802.3ae 10 Gigabit Ethernet Task Force, XAUI delivers 10 Gb/s of data throughput using four differential signal pairs in each direction.

net Task Force developed the XAUI interface. XAUI is a full duplex interface that uses four (4) self-clocked serial differential links in each irection to achieve 10 Gb/s data throughput. Each serial link operates at 3.125 Gb/s to accommodate both data a

The AMD 10 Gigabit Attachment Unit Interface (XAUI) LogiCORE™ IP provides a 4-lane high speed serial interface, providing up to 10 Gigabits per second (Gbps) total throughput.

The Xilinx® LogiCORETM IP eXtended Attachment Unit Interface (XAUI) core is a high-performance, low-pin count 10-Gb/s interface intended to allow physical separation between the data link layer and physical layer devices in a 10-Gigabit Ethernet system.

XAUI is a specific physical layer implementation of the 10 Gigabit Ethernet link defined in the IEEE 802.3ae-2002 specification. The XAUI PHY uses the XGMII interface to connect to the IEEE802.3 MAC and Reconciliation Sublayer (RS).

Use of robust simple SerDes interface meets 40G/100G technical requirements and schedule objectives. XLAUI/CAUI allow the standard to move forward by eliminating interdependencies of different PMD type.

The Lattice Semiconductor XAUI 10Gb Ethernet Interface IP provides a solution for bridging between XAUI and 10-Gigabit Media Independent Interface (XGMII) devices.

XGMII is a 156.25 MHz Double Data Rate (DDR), parallel, short-reach interconnect interface. It supports interfacing to 10 Gbps Ethernet Media Access Control (MAC) and PHY devices.
