ABSTRACT:
A method and system for monitoring a frequency of a clock signal is disclosed. The method and system comprise dividing a clock signal into a plurality of clock signal components. The method and system further comprise adding a delay to each of the clock signal components and comparing the plurality of signal components with each of the delayed clock signal components to monitor whether the clock signal is within a predetermined frequency range. The method and system includes providing an output signal indicative of a condition of the clock signal based upon the comparing step.
