Xilinx provides a no charge Dune Network compliant RXAUI core to ensure first time success in your design.

Free paramaterizable core that utilizes the Virtex®-6 GTX Transceivers to support the RXAUI function.

The Xilinx Reduced 10 Gigabit Attachment Unit Interface (RXAUI) LogiCORE™ IP provides a 2-lane high speed serial interface at 6.25 Gbps, providing up to 10 Gigabits per second (Gbps) total throughput compliant with Dune Networks RXAUI specification. Operating at an internal clock speed of 156.25 MHz, the core includes the XGMII Extender Sublayers (DTE and PHY XGXS), and the 10GBASE-X sublayer, as described in clauses 47 and 48 of IEEE 802.3-2005. In addition, the core supports an optional serial MDIO management interface for accessing the IEEE 802.3-2005 clause 45 management registers. The MDIO interface may be omitted to save logic, in which case a simplified management interface is provided via bit vectors.

Key Features

  • Designed to Dune Networks RXAUI specification
  • Interoperability tested with Dune Networks device
  • Uses two Virtex-6 FPGA GTX transceivers at 6.25 Gbps line rate to achieve 10-Gbps data rate
  • Implements DTE XGXS, PHY XGXS, and 10GBASE-X PCS in a single netlist
  • Uses Virtex-6 FPGA Mixed-Mode Clock Managers
  • Uses device-specific transceivers for the RXAUI interface
  • IEEE 802.3-2005 clause 45 MDIO interface (optional)
  • Available under End User License Agreement
 
What features does the RXAUI IP core support?
  • The RXAUI core is delivered through the CORE Generator™ and may be configured by the user with the following options:
    • Optional MDIO interface, or simplified interface with configuration vector for the Dune or Dune Alternate modes of operation
      Because the core is parameterized through the CORE Generator, you can tailor the core to your specific feature set requirements.
Which Xilinx FPGA families and speed grades does the RXAUI core support?
  • RXAUI Device Support - Virtex®-6 LXT, SXT, HXT -2 Speed grade or higher
Which Xilinx Software version supports this core?
  • Please see the data sheet for the latest supported software version.
What are the target applications for this product?
  • The RXAUI core is ideally suited for :
    • Bridging applications - applications requiring the transfer of Ethernet frames across a medium different from Ethernet, where protocol termination is not required (Examples: switch port interfaces).
    • Interfacing 10 Gigabit Ethernet to other standard interfaces (e.g., SPI-4.2).
    • Backplane applications which require 10 Gbps data rates.
    • Chip-to-chip or board-to-board 10G interfaces
What PHYs is the RXAUI core compatible with?
  • The RXAUI Core is designed to be compatible with industry standard PHYs which comply with Dune Networks RXAUI specification.
What is the availability, cost and licensing terms for the RXAUI core?
  • The RXAUI core is provided free of charge and is available now. The parameterizable core is configured through a CORE Generator™ GUI and licensed via the Xilinx End User License Agreement. License key generation is found on the product page for this core. See the left side bar also for Instructions for downloading the core.
Has the RXAUI core been verified on hardware?
  • Virtex-6 LXT devices configured with RXAUI interfaces have been successfully tested for interoperability with Dune Networks.
Are there any features that can be omitted to reduce the resource utilization of the core?
  • The following features may be omitted when customizing the RXAUI core via the CORE Generator: MDIO Management interface
What is the impact of these optional features on slice utilization?
  • Please refer to the device utilization section of the datasheet.
How can I evaluate the core?
  • The IP access is provided at no charge. To generate a license key, please select Get License from the product page.
What other Ethernet solutions does Xilinx provide?
  • See the IP Release Notes for known issues, new features and patches.
Where can I find a list of Known Issues?
  • The RXAUI core is part of the Xilinx Platform FPGA SystemIO solution, which addresses all aspects of system connectivity in high-performance designs. Xilinx provides the most comprehensive Ethernet MAC offerings in the programmable industry. In addition to the RXAUI core, Xilinx also provides an Ethernet 1000BASE-X Adapter core for 1 Gbps applications. Additionally, Xilinx also offers these Ethernet solutions:
