INTRODUCTION

The 3G-SDI to USB 3.0 Video Capture device is used to record or stream an SD/HD/3G-SDI signal via USB 3.0 at up to 350
MB/s. It features an HDMI loop output for local display, as well as separate 3.5mm stereo audio input/output connectors.
Features:

Converts SD/HD/3G-SDI and stereo audio input signals to high quality USB 3.0 output
Automatic input equalization – compensates for attenuation on the incoming signal and automatically equalizes
o
cables for the following distances using 75 Ohm RG6 BNC cables:

3G-SDI 1920x1080 @60Hz to 328 feet (100 meters).

HD-SDI 1280x720 @60Hz to 656 feet (200 meters).

SD-SDI 525i @60Hz and 625i @50Hz to 984 feet (300 meters).
Automatic output reclocking – reshapes and restores timing of digital video signal at output, eliminating high
o
frequency jitter.

