Video Output Electrical Specifications

The VIDEO connector has one Video Output port.

Each port has two pins named VID_OUT and VRN_OUT respectively. The "hot conductor" of the transmission line transporting the video signal has to be connected to the VID_OUT pin, while the "cold conductor" of the transmission line has to be connected to the VRN_OUT pin. If the transmission line is a coaxial line, the "hot conductor" is the inner conductor, and the "cold conductor" is the outer conductor.

The output of the Video Output multiplexer is low-pass filtered, then amplified by a video buffer with a fixed gain of 2.

The output of the buffer is AC-coupled and serially terminated by a 75Ω termination resistor inserted in the output path.

The video output is further filtered by a common-mode choke, which prevents common-mode noise present on the video signal to penetrate inside. The VRN_OUT pin is connected to the analog GND through one winding of the common-mode choke. The VID_OUT pin is connected to the second winding.
