Abstract
A clock generator system includes a first clock generator circuit to generate a first clock output signal having a first clock output frequency that is within a first bounded range of frequencies. The first clock generator circuit, during a transition mode, exhibits a first ramping of the first clock output signal from the first clock output frequency towards a target frequency. The system includes a second clock generator circuit to generate a second clock output signal having a second clock output frequency that is within a second bounded range of frequencies. The second clock generator circuit, during the transition mode, exhibits a second ramping of the second clock output signal from a second frequency towards the target frequency. A controller coupled to the first clock generator circuit and the second clock generator circuit selectively passes one of the first clock output signal or the second clock output signal as a system clock output signal. The controller, upon a desired change from a first system clock output frequency to the target frequency, switches from the first clock output signal to the second clock output signal at a dynamically-determined frequency crossover threshold.
