The Video Splitter is an extremely high performance 1-input, 2-output analog video distribution amplifier designed to split a single RGBHV signal into two paths. The Video Splitter is intended for applications that require absolutely no signal degradation when one video source must be sent to two destinations. This device has separate amplification circuitry for each output, avoiding a signal degradation problem commonly encountered when splitting a video signal. The amplifier circuitry within the Video Splitter provides 75 Ohm termination to avoid reflections and a fast slewing amplifier to maintain a quick settling time. Both of these are imperative for maintaining proper video signal integrity.

A typical application for the Video Splitter is for the testing and verification of VGA-based computer systems. Users may require the video source to be simultaneously input to a board for acquisition and to another monitor for display. Additionally, any time that a video signal has to travel a considerable distance and be split, the Video Splitter may be necessary to maintain signal quality. With the Video Splitter, the signal is buffered and then amplified back to the proper video level without altering the signal integrity to either of the two target devices.
