Please note this is an Used Snell IQSYN20 HD/SD-SDI Frame Synchronizer. ES Broadcast carefully tests all used equipment prior to sale, and offers a three-month warranty. Images shown are for illustrative purposes only and may not be of the specific model offered for sale. Accurate pictures of this model are available on request.

Snell IQSYN20 provides synchronization for HD-SDI 1.5 Gbps or SD-SDI 270 Mbps signals.

Using agile synchronization that is router switching tolerant makes this module ideal for lines input applications using SDI video signals. A video processing amplifier provides complete control over the video levels, and additional video delay is available.
A particularly powerful feature for constructing simple solutions to difficult system problems is the router at the input to the synchronizer. That means that the IQSYN20 can easily be placed at the end of main and redundant feeds or be used where an HD-SDI feed is complemented by an up-converted SD-SDI or even a digitized and up-converted analog feed.


  • Agile HD/SD-SDI synchronizer capable of referencing to a bi-level or tri-level reference
  • Dual selectable HD/SD-SDI inputs with auto switching
  • Agile synchronizer locking capable of handling mis-timed inputs of up to 5 lines without output video disturbance (SMPTE RP168 compliant)
  • Standards supported:
  • HD-SDI to SMPTE 292M/274M/296M
  • SD-SDI to SMPTE 259M-C
  • Precision wide range genlock adjustment allowing you to time any HD/SD-SDI signal to pixel accuracy
  • Independent horizontal and vertical ancillary data blanking
  • Input loss detection – input pass through/switch or black/pattern/freeze and Input SDI, CRC, EDH and ANC data checking and reporting
  • Emergency input bypass option enables the SDI input signal to be passed through to
  • SDI output 1 in the event of frame power failure or module removal
  • Can be used as a video delay without synchronization, up to 1 frame
  • Video processing controls including video gain and offset
  • In-built test pattern generator
  • 16x user memories

Inputs and Outputs
Signal Inputs
SDI Inputs 2x HD/SD-SDI
Electrical 1.5 Gbps HD-SDI, SMPTE 292M 270 Mbps SDSDI, SMPTE 259M-C
Connector / Format BNC / 75 Ohm panel jack on standard Snell connector panel

Note: Specified cable lengths are a guide only. Exact cable length performance will depend on the quality of the cable used, the SDI video rate and the system setup. It is advisable not to cascade modules using the relay rear version although it may be possible if the interconnecting cable lengths are kept to an absolute minimum.
