The 3G-SDI Professional Interface

Sparrowhawk FX Video Processing Board includes an expansion connection to support applications that can be implemented using SERDES. This expansion connection uses two whole SERDES quads available with 4 SERDES inputs and 4 outputs for expansion as SDI, or other video interfaces, the control/status signals, audio channels over IO pins and the power/ground pins.

The SDI Add-on board is a Sparrowhawk FX video processing board daughter card designed to support Serial Digital Interface (SDI) family of video interfaces standard from the Society of Motion Picture and Television Engineers (SMPTE) that transmits digital video data and embedded audio data through the 75-ohm coaxial cable.

Key feature set

  • Advanced broadcast and surveillance applications
  • SD-, HD- and 3G-SDI Input/output
  • Studio Genlock input for broadcasting applications
  • Audio embedding/extraction



Commercial application

  • Broadcast equipment
  • Professional video
  • Industrial video systems
  • Machine vision
  • Surveillance
  • DVRs


The Sparowhawk FX SDI Add-on board includes the most common interfaces for broadcasting such as:

Video interfaces like four SD-/HD-/3G- SDI Input through the SDI Equalizer and four SD-/HD-/3G- SDI Output,

Audio interfaces like AES-3id IN & OUT, as well as  and Stereo analog IN & OUT and FPGA to ADC interface.

Also, the SDI Add-on board features studio Genlock input for broadcasting applications with black burst and tri level sync.
