VIDEO SWITCHING CONTROL CARD

Video Switching Control Card is a custom Designed card with controls for switching of two channel video input. Each of the channels has two video inputs, which are processed identically. The video inputs are given to an Analog comparator to generate TTL controls for external RF Switch and to a 2:1 video multiplexer used for selection of the video source. The analog comparator compares the magnitude of the two video inputs on the channel and produces a digital control output. This output is used as select to a 2:1 Multiplexer and also buffered to be used as switching control for the RF switch. The selected Video output from the multiplexer is amplified and made available on the PCB mount 30 pin Airborne Connector
