Explain the function principle of VGA splitter

The VGA splitter is designed to take a single video input and distribute it to multiple video outputs, ensuring that the video remains clear, undistorted, and maintains its original resolution. In addition to providing multiple independent outputs, many VGA splitters also include signal amplification, which helps maintain signal strength over longer distances. This makes them not only splitters but also video distribution amplifiers.

The VGA splitter offers independent 4- to 6-channel output capabilities, each with a 75-ohm load. These outputs are typically driven by isolated complementary transistors or dedicated video amplifier ICs, ensuring signal integrity. The device supports broad frequency response, compatibility with standard video formats, and features BNC inputs and outputs for reliable connections.

A single VGA video distributor takes one video signal and splits it into multiple outputs. Each output maintains the same bandwidth, peak-to-peak voltage, and output impedance as the input signal. A single input can be split into two, four, eight, twelve, or even sixteen identical outputs, allowing the signal to be sent to various video processors or displays without degradation.

This type of distributor splits one video input into up to four outputs, and can further expand to eight, twelve, or sixteen outputs when using multi-input configurations. It reduces the need for multiple individual units, making the system more compact and stable. Each input channel can support two, three, or four identical outputs for use in other parts of the video system.

An octal VGA splitter distributes one video signal across eight channels, and can expand to sixteen, twenty-four, or thirty-two outputs depending on the setup. By using a multi-input configuration, it minimizes the number of separate distributors required, thus reducing overall equipment size and improving system reliability. Each input can be divided into two, three, or four identical outputs for further processing.

This high-capacity distributor takes one video input and expands it to 32, 48, or 64 outputs, depending on the model. It’s ideal for large-scale video distribution systems where multiple displays or devices need the same source. Using a multi-input design, it reduces the number of individual units needed, resulting in a more efficient and stable system. Each input can be split into two identical outputs for use in different parts of the setup.
