Altera'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.
