Datavideo VP-633/634SDI Repeaters A powered SDI repeater

The VP-633 is a powered inline repeater that reclocks and re-drives a 3G/HD/SD-SDI signal, extending a single SDI cable run out to 100 meters without losing the embedded audio. It regenerates the signal rather than merely boosting it, so the picture that arrives downstream stays clean.

For longer runs, an unpowered VP-634 can be added for each additional 100 meters, chaining a VP-633 plus up to three VP-634 units for roughly 1000 meters on good cable. The VP-633 ships with a 12V DC power supply and presents a 75 Ohm impedance in a compact metal body.
