External Sync Module
Technical Specification
The External Sync Option card provides a means of inputting a system reference either from an external, 10MHz clock or analog
video source. Only one reference source may be connected at any time, and the single BNC connector caters for either input signal
type.
Input (Analog Video)
The input is capable of accepting a wide range of analogue video input voltage levels and is also capable of accepting various colour
standards. Requirements for the video input signal are defined in the following table.
Input (10MHz Reference)
A 10 MHz input can be applied via the BNC connector which may be sinusoidal or square in shape.
The required characteristics for the input signal are defined in the following table.
