Abstract:
Devices, systems, and methods for spread spectrum clock generation are disclosed. The devices, systems, and methods generate a clock signal at a frequency and generate a voltage output based on the frequency of the clock signal, wherein the generated voltage output is indicative of the frequency of the generated clock signal.

Abstract:
In one implementation an output signal of an oscillator is varied to be within a desired frequency band with respect to a reference signal, the output signal having a plurality of phases. The implementation may include comparing the output signal with the reference signal, counting falling edges about each phase of the number of phases in a predetermined time period and summing to define a count output; comparing the count output with a product of the number of phases of the output signal and the factor to define a comparison, generating a control signal based upon the comparison, and inputting the control signal to the oscillator to alter the output signal thereof.
