Type DDA-4009 Serial Digital Data Distribution Amplifiers from IRT Electronics

Supplier News

IRT Electronics  supplies DDA-4009 range of serial digital data distribution amplifiers designed for application in various distribution and monitoring functions.  

Type DDA-4009 distribution amplifiers offer the user a single module to cover a wide range of distribution and monitoring functions for 3G/HD/SD-SDI, ASI or STM-1 signals.  

Two quad output reclocking/ non-reclocking distribution amplifiers are provided on one card. On-board switch settings allow either of the inputs to feed all outputs to create a one-in, eight-out distribution amplifier.  

Where non-reclocking is required, on-board switch settings select between reclocking and non-reclocking modes.  

DDA-4009 distribution amplifiers will automatically reclock to match the input at 3G-SDI, HD-SDI, SD-SDI, ASI or STM-1 rates or can be fixed to operate at any one of these rates.  

Both sides of the DDA-4009 can be run independently allowing a mixture of signal types.  

Front panel LEDs indicate the presence of input signals and whether the outputs are locked to the inputs.  

An optional relay bypass rear assembly is available to switch one of the inputs to one of the outputs in the event of a power failure.  

Simple Network Management Protocol (SNMP) is available for remote setup and monitoring of input status as well as alarm states when used in an IRT frame fitted with SNMP capability.  

The DDA-4009 distribution amplifiers are designed to fit IRT’s 4000 series 3RU frame for use with IRT’s SNMP system in addition to being suitable with IRT’s 1000 series 1RU Eurocard frames and may also be used alongside any other of IRT’s Eurocards.  

Key features:

  • 4 in-phase reclocked/ non-reclocked outputs on each amplifier
  • Switch selectable for 1-in, 8-out single distribution amplifier operation
  • Selectable for 3G/HD/SD-SDI, ASI or STM-1 applications
  • Automatic output muting on no input
  • Optional relay bypass on loss of power
  • Front panel indicators monitor presence of inputs and lock status
  • SNMP monitoring and control
