Intel's XAUI PHY IP core implements the IEEE 802.3 Clause 48 specification to extend
the operational distance of the XGMII interface and reduce the number of interface
signals.
XAUI extends the physical separation possible between the 10 Gbps Ethernet MAC
function and the Ethernet standard PHY component to one meter. The XAUI PHY IP
core accepts 72-bit data (single data rate–SDR XGMII) from the application layer at
156.25 Mbps. The serial interface runs at 4 × 3.125 Gbps.

Intel's third-party IP partner for Dual Data Rate XAUI (DDR XAUI or DXAUI) and
Reduced XAUI (RXAUI) support is MorethanIP (MTIP).
