Explain the function principle of VGA splitter

A VGA splitter is a device that takes one video input and distributes it to multiple outputs, ensuring that the video remains clear, sharp, and free from distortion or loss of quality. In addition to providing multiple independent outputs, VGA splitters often include signal amplification capabilities, which makes them function as video distribution amplifiers. This feature ensures that the signal strength remains consistent across all outputs, even over long distances.

The VGA splitter offers independent 4- or 6-channel output configurations with 75 ohm load capability, using either isolated complementary transistors or dedicated video amplifier ICs. These designs ensure signal integrity, compatibility with various display devices, and a wide frequency response range. The device typically includes BNC input and output terminals for reliable connections.

Common Equipment:

Single VGA Video Distributor

This device takes a single VGA video signal and distributes it to multiple outputs, maintaining the same bandwidth, peak-to-peak voltage, and output impedance as the original input. It supports two-way, four-way, eight-way, twelve-way, and sixteen-way output configurations, allowing the same high-quality signal to be sent to multiple displays or processors.

Quad VGA Video Distributor

Designed for four-channel distribution, this unit can split a single video signal into up to eight, twelve, or sixteen outputs. It allows for multi-input operation, reducing the need for multiple individual splitters. Each channel can support two, three, or four identical outputs, making it ideal for complex setups where system stability and compact design are essential.

Octal VGA Video Splitter

An octal VGA splitter is capable of distributing a single video signal across 16, 24, or 32 outputs. By supporting multi-input functionality, it minimizes the number of separate units required, resulting in a more compact and stable system. Each input channel can be configured to produce two, three, or four identical outputs, enhancing flexibility for various applications.

16-Channel VGA Video Distributor

This advanced distributor takes a single 16-channel video signal and expands it to 32, 48, or 64 outputs. It uses multi-input technology to reduce the overall number of splitters needed, helping to save space and improve system reliability. Each input can be set to produce two identical outputs, ensuring consistent performance across all connected devices.
