The Lattice Semiconductor 10Gb Ethernet Attachment Unit Interface (XAUI) provides a solution for bridging between XAUI and 10-Gigabit Media Independent Interface (XGMII) devices. The IP core implements the 10Gb Ethernet Extended Sublayer (XGXS) capabilities in soft logic that together with PCS and serializer/deserializer (SERDES) functions implemented in the FPGA provides a complete XAUI-to-XGMII solution.

Latest Resource Utilization details are available in the IP Core User Guide.

Features

  • XAUI compliant functionality supported by embedded PCS implemented in the CertusPro-NX device, including four channels of 3.125 Gbps SERDES with 8b10b encoding/decoding.
  • Complete 10Gb Ethernet Extended Sublayer (XGXS) solution /li>
      TX phase FIFO and TX clock compensation FIFO
    • 10 GbE Media Independent Interface (XGMII).
    • XAUI compliant lane-by-lane synchronization.
    • Lane de-skew functionality.
  • Supports AMBA 3 APB interface for CertusPro-NX and Avant-AT-G/X devices, and AXI4-Lite interface for Avant-ATG/X devices.
