1. Introduction
2. Features
The VDA-104-3GS-2 receives one SDI input, perfectly duplicates it, and re-transmits four SDI
outputs for real time multi-viewing. It is a reliable video device splitting a SDI, HD-SDI, or 3G-SDI
video source to four SDI compliant displays at the same time. Besides, built-in re-clocking &
equalization features provide the best performance for SDI distribution ampliļ¬er.
ā¢ 3G/HD/SD triple-rate distribution
ā¢ Four separately buffered and re-clocked outputs
ā¢ Supported SDI format
Ā» 3G-SDI (SMPTE 424M, 425M level A,B up to 2.97 Gbps)
Ā» HD-SDI (SMPTE 292M, 296M up to 1.485 Gbps)
Ā» SD-SDI (SMPTE 259M, up to 270 Mbps)
ā¢ Cable equalization (Belden 1694A) and signal retiming
ā¢ Video bandwidth: 2.97Gbps, 2.97/1.001Gbps
ā¢ Automatic detection of 3G/HD/SD-SDI signals
ā¢ Dual color LED indication of input lock and rate
ā¢ Passes all ancillary data
ā¢ Provides automatic cable equalization
Ā» [3G-SDI]* >120m (394ft)
Ā» [HD-SDI] >200m (656ft)
Ā» [SD-SDI] >300m (984ft)
ā¢ Re-clocks SDI signals for cascading and thus longer transmission
ā¢ Inter-locked power supply for better ļ¬xedness
Note: The cable length depends on the characteristics and quality of the cables.
