4.5. XAUI

To implement a XAUI link, instantiate the XAUI PHY IP core in the IP Catalog, under Ethernet in the Interfaces menu. The XAUI PHY IP core implements the XAUI PCS in soft logic.

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). The IEEE 802.3ae-2002 specification requires the XAUI PHY link to support a 10 Gbps data rate at the XGMII interface and four lanes each at 3.125 Gbps at the PMD interface.
