1.2 SDI Input (J6 and J7) The EB-GS3471-00 includes two 3G-SDI inputs DC-coupled to the GS3471. The applied video stream will first pass through Semtech's GS3140 Cable Equalizer (PDS-060939) before entering the DDI input pin of the GS3471. The pin J6 provides a DC path to the GS3471 through the GS3140, while the pin J7 provides a direct AC path to the GS3471. -
