  • Page 4: Module Overview

    Model 7450 HD Protection Switch MODULE OVERVIEW The 7450 module is a fail-safe, bypass protection switch for critical digital paths for broadcast or satellite applications. When a fault is detected in the primary input, and the secondary input is veri ed as good, the switch will activate, causing the secondary input to be switched to the module’s output.
  • Page 5 Model 7450 HD Protection Switch Small Window which is approximately two thirds of the picture width and height, or Big Window which covers approximately 90% of the width and height. This allows a corner Bug to be either excluded or included in the detection process. Black detection is performed on a pixel-by-pixel basis within the selected window, with user selectable Detect Level and Blk Frac adjustments.
  • Page 6 Model 7450 HD Protection Switch Each of the signals is fed to identical detection circuits which evaluate multiple parameters and characteristics of the signal in order to arrive at a fault decision. Detection of TRS errors is done in a Receiver/Reclocker circuit which produces a reclocked serial output feeding a Deserializer circuit.
