Abstract:
Techniques are disclosed relating to rapidly downshifting the output frequency of an oscillator. In some embodiments, the oscillator is configured to operate in a closed-loop mode in which negative feedback is used to maintain a particular output frequency (e.g., in a phase-locked loop (PLL)). In some embodiments, the negative feedback loop is configured to maintain the output of the oscillator at a particular frequency based on a reference clock signal and the output of the oscillator. The nature of a negative feedback loop may render rapid frequency changes difficult, e.g., because of corrections by the loop. Therefore, in some embodiments, the loop is configured to switch to an open-loop mode in which a control input to the oscillator is fixed. In some embodiments, the loop switches to open-loop mode in response to a trigger signal and control circuitry forces the oscillator to a new target frequency.

Claim (Index 1):
An apparatus, comprising:\n an oscillator configured to generate an output clock signal based on one or more control signals; feedback circuitry configured to control the oscillator based on the output clock signal; and sensor circuitry configured to output a trigger signal; wherein the apparatus is configured to use the oscillator to provide the output clock signal to processor circuitry, wherein the processor circuitry is configured to processes instructions based on the output clock signal in both:\n a closed-loop mode in which the feedback circuitry is configured to vary at least one of the one or more control signals based on both the output of the oscillator and a reference signal to cause the oscillator to generate the output clock signal at a first frequency; and \n an open-loop mode in which the oscillator generates the output clock signal at a second frequency that is lower than the first frequency, without feedback based on output of the oscillator; \n wherein the apparatus is configured to transition from the closed-loop mode to the open-loop mode in response to the trigger signal.
