openGear 2x4 or 1x8 3G-SDI Reclocking DA


An openGear Ditribution Amplifier, with 4 re-clocked outputs for each of the two 3G-SDI inputs on the card

£514.00 £616.80

The OG-2x4-SDI-DA is an openGear-compatible, state of the art 3G-SDI distribution amplifier. The incoming 3G-SDI signals on the 2 input channels are reclocked and distributed to 4 x 3G-SDI outputs each, or alternatively can function as a 1 x 8-Channel DA, allowing the same signal to be sent to eight destinations simultaneously. This dual input capability allows double the number of DAs in limited frame space. A 10 BNC rear Open Gear connector module is included.


  • Input: 2 x 3G-SDI, BNC connector (2 x 4 mode)
  • 1 x 3G-SDI, BNC connector (1 x 8 mode)
  • Outputs: 4 x 3G-SDI each DA, BNC connector (2 x 4 mode)
  • 8 x 3G-SDI, BNC connector (1 x 8 mode)
  • Automatic cable equalizer and automatic reclocker bypass
  • Automatic detection and reclocking of 270Mb, 1.5Gb, and 3Gb SDI data rates
  • Advanced jitter input tolerance and low jitter reclocked outputs
  • Power: 2.0 watts max per card
  • Hot swap capable
  • Compatible with DFR-8321 and OG3 openGear frames


The 3G-SDI inputs are equalized and re- clocked with best-in-class cable length capability and input jitter tolerance. SDI rates of 270Mb, 1.5Gb, and 3Gb are supported. Two SDIs input and 8 SDI outputs are provided. A 10-BNC rear openGear connector module is included.

openGear Compatibility

The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rackframe products.

Flexible I/O

The modular rear panel allows custom I/O connections per card (included with individual cards).



The optional redundant power supply provides a secondary power source in the event of a primary power failure.

Ethernet Access

A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.
