| - | ===== Experimental VGA Processor ===== | ||
| - | |||
| - | This VGA board makes mixing of all kind of signals possible. Video, audio and all kind of other signals can be mixed together. And because the operational amplifier [[https://www.analog.com/media/en/technical-documentation/data-sheets/12596fas.pdf|LT1260]] can handle signals up to a frequency of 130Mhz it's ideal to mix analog video signals, too.\\ | ||
| - | The board has two VGA connectors, one for input and the other for the output. An audio signal can be taken from the pins near the VGA output. The VGA connector for the input bypasses the Sync signal to the output. For other inputs like other VGA sources or audio signals there are three potentiometer and three extra pins reserved.\\ | ||
| - | If one has two synced video sources the Experimental VGA Processor could be used to blend these two videos.\\ | ||

| - | If one use long pin strips for the input connection the Experimental VGA Processor could be easily combined with a bread board. In this combination it's a perfect experimental setup to explore and mix all kind of signals.\\ | ||
