Abstract
An active fail-safe method and apparatus for a LVDS receiver that uses a window comparator circuit to monitor the differential voltage at the receiver's input pins and drive the output to a known logic HIGH state in the absence of a valid input signal; i.e., when the input differential signal is less than a chosen threshold value of approximately 80 mV. Such a condition may occur when the cable is removed or damaged in such a way that no valid input signal is present. In the presence of a valid input signal, the circuit's output tracks the differential input without any degradation to the signal.
