HD-SDI Repeaters for Long-Distance Digital HD-CCTV Extend HD-CCTV Links up to 1.0 km with Power Over Cable and Camera Control Link Over Single Coax Cable Implementation Each repeater supports a data rate of 2.97 Gbit/s (3G-SDI). A link of up to 220m can be achieved with a data rate of 1.485 Gbit/s, depending on cable quality*. For longer cable lengths, lower speed camera are supported. For example, a cable length of 720m supports SDI cameras. Up to five repeater units can be daisy chained together, all powered over the coax cable by the first repeater. The repeater nearest the recorder can be provided with the system power and the camera control signals. Similarly, the control signals and power (if needed) can be fed to a camera by the nearest repeater to it. Camera control is accomplished via RS485, the most commonly used Summary communications protocol. It supports a control signal Microchips EQCO-SDI30-7501 is an extender solution for bandwidth of up to 38.4 kbps. HD-SDI links, operating over a standard 75 coax cable. Each unit receives an attenuated HD-CCTV signal and DVR Side Repeater Including Link Power extends it up to 220m over the coax cable. and Control Channel The repeater contains three critical components to correct To DVR From Camera and then retransmit the signal: HD-SDI Adaptive Equalizer to return the signal to its original Repeater amplitude and modulation Reclocker to resynchronize the signalbringing it back Power AC Adapter to its original condition Control Cable Driver to retransmit the signal with its original characteristics restored The repeater design offers these unique benefits: Power can be transmitted from the recorder (DVR) side In-Line HD-SDI Repeater to the camera over the coax cable Up to ve repeaters may be powered from the rst HD-SDI repeater at the DVR side over the cable if only one or Repeater two repeaters are used, the remaining power may also be adequate to power the SDI camera at the remote end A control signal (RS485) can be transmitted from the recorder (DVR) side to the camera over the coax cable The repeater enables simultaneous signal transmission camera control, and power, over a single cable.
