VA6822 DESCRIPTION

4

The VA6822 has two key functions. First, it amplifies (buffers) the input video and audio signal so that it is strong enough to travel long distances up to 350ft through high quality cables to a distant display and audio receiver. The second function of the VA6822 is to process the incoming sync signal and convert it to a format that is accepted by a projector. The computer and projector should be scan-rate compatible.

4.1COMPUTER VIDEO INPUT (VGA-

COMPATIBLE 15-PIN HD CONNECTOR)

The 15-pin HD connector input allows the connection of a computer to the system interface using ALTINEX-made input cables which are available for a variety of popular computers and graphics cards on the market such as VGA, MAC, SUN, and SGI. The input of the VA6822 is compatible with VESA standard-VGA/XGA, which is shown below.
