TX Core

The New Wave DV Streaming Pixel-Bus to ARINC 818 IP Core provides a streaming conversion from a pixel bus into an ARINC 818 formatted FC serial data stream.

All aspects of maintaining a fibre channel link is handled by the core. As the incoming data is converted into FC packets, the core adds the necessary header, delimiters (SOF, EOF) and calculates and inserts the FC CRC. FC headers are calculated and updated for each frame by the core. The core also manages inserting IDLE characters in between packets as needed and when the link is unused. The core will convert the outgoing data stream into 8b/10b encoding (automatically managing running disparity). No user intervention is required to establish and maintain a fibre channel link.

The core will maintain and regulate timing parameters including frame rate, video line rate, and FC packet spacing. Timing parameters are flexible and can be user adjusted in single clock cycle increments. The core supports all standard Video Rates (30Hz, 50Hz 60Hz, etc.) and non-standard video rates are possible as well. Configurable line rates and inter-fc packet spacing allows the designing adjust the utilized throughput of the FC link to match their system.

While the core will automatically calculate and maintain the ARINC 818 Object 0 container header, the Object 0 ancillary data can be user controlled. Memory space is allocated for users to create and update the Ancillary data and can be done completely asynchronously from the video transfer. The total size of the ancillary data (up to the limits of a FC frame) is user defined allowing the user the flexibility to include custom meta data in their ARINC 818 stream.

RX Core

The New Wave DV ARINC 818 to Streaming IP Core provides a streaming conversion from ARINC 818 formatted FC data into a pixel bus.

All aspects of maintaining a fibre channel link are handled by the core. The incoming data is decoded, parsed, and unpacked. A timing engine in the core adds flags to indicate the start of a frame (vsync) and the start of each row (hsync).

Timing parameters such as frame rate and line rate do not need to be prespecified. The core will automatically adapt to the incoming data and pass through converted data at the rate that it is input to the core. The core is compatible with all standard video rates (30Hz, 50Hz, 60Hz, etc.) as well as non-standard rates.

The core makes the entire Object 0 frame available to the user in memory space. The memory space will include the FC header, the container header, and any Object 0 ancillary data. The user can access this data at any time, asynchronously from the packet streaming process. The memory space will be updated with each new Object 0 frame.


  • Flexible video pixel bus input with synchronization signals (video_active, vsync, hsync) that supports a wide range of pixel depths and number of parallel pixels
  • Compatible with all FC line rates up to 10G (incl. non-standard rates)
  • Core handles synchronization and clock crossing into the FC clock domain. User clock can be asynchronous to the FC clock
  • Automatic creation and maintenance of the Object 0 and container header
  • 8b/10b encoding/decoding of FC data. Core manages K-Characters and running disparity


  • RX (Receive) and TX (Transmit) functionality included
  • User-configurable frame rates, line rates, and ADVB frame spacing
  • Built-in timing engine controls/regulates timing in hardware
