The SDI-VIT-75 is a video isolation transformer for eliminating hum in serial digital transmission lines. This can be used for Broadcast Systems where hum is present due to ground loops or where there is a large differences in ground potential. The SDI-VIT-75 provides electrical isolation between the input and output and will also eliminate induced currents in long cable runs. It can supports all transmission rates of SMPTE259m and ITU-R BT 656. Supports 143Mbps to 540 Mbps including 270Mbps transmission rate.
