GeckoFlex 8943RDA-D Dual 3G/HD/SD Reclocking Distribution Amplifier

The 8943RDA-D is a dual-input HD/SD/3G-SDI reclocking distribution amplifier. It provides two electrical inputs that can be mapped to feed any of four reclocked electrical output pairs (one input per output pair). The board is also completely DVB ASI compliant.

It can distribute either HD/3G-SDI or SD-SDI, making it ideal for mixed-format applications or installations where an upgrade to HD/3G-SDI is planned. Up to 90 meters for input 1 (J9), 100 meters for input 2 (J10) of Belden 1694A cable can be equalized for HD/3G-SDI and up to 440 meters for SD-SDI.

All parameters can be configured directly from the card edge or via a standard HTML web browser when the 8900NET Network Interface board has been installed. The board operation and configuration, as well as the signal presence and format, can be monitored using industry standard SNMP protocol via the 8900NET board.

  • Supports HD/SD/3G-SDI rates up to 1080p
  • Two electrical inputs
  • Four electrical reclocked output pairs
  • Configurable input to output pair mapping
  • Auto or manual input format selection
  • 100% DVB ASI compliant
  • High density (up to twenty DA inputs per 2 rack units)
  • Remote control and monitoring via Ethernet chassis interface
  • Distributing HD/3G signals or mixed HD/3G and SD format installations
  • Installations where an SD to HD/3G update is planned
  • Installations where highest density is required at the lowest cost
  • For optimizing and adapting trade-off between number of DAs and number of outputs
Supported Chassis Types
GeckoFlex chassis
