GeckoFlex 8943RDA 3G/HD/SD Reclocking Distribution Amplifier

The 8943RDA is an HD/SD/3G-SDI reclocking distribution amplifier with one electrical input feeding eight reclocked electrical outputs. The board is completely DVB ASI compliant.

This board can distribute HD/3G-SDI or SD-SDI, making it ideal for mixed-format applications or installations where an upgrade to HD/3G is planned. Cable equalization is up to 90 meters for HD/3G-SDI and 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.

  • Reclocking SD-SDI, HD-SDI, and 3G-SDI distribution amplifier
  • Auto or manual input format selection
  • Supports rates up to 1080p
  • Single 1x8 DA
  • 100% DVB ASI compliant
  • High density (up to ten 1x8 DAs 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
