2.6.6. XAUI PHY IP Core

In a XAUI configuration, the transceiver channel data path is configured using a soft PCS. The XAUI configuration provides the transceiver channel datapath, clocking, and channel placement guidelines. You can implement a XAUI link using the IP Catalog. Under Ethernet in the Interfaces menu, select the XAUI PHY IP core. 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-2008 specification. The XAUI PHY uses the XGMII interface to connect to the IEEE802.3 MAC and Reconciliation Sublayer (RS). The IEEE 802.3ae-2008 specification requires the XAUI PHY link to support:

  • A 10 Gbps data rate at the XGMII interface
  • Four lanes each at 3.125 Gbps at the PMD interface
