Abstract
In some embodiments, a circuit includes an oscillator circuit, a control circuit, and a synchronization circuit. The oscillator circuit generates a clock signal and includes a selectable delay circuit. The control circuit receives the clock signal from the oscillator and a reference signal. The control circuit provides a control signal to the synchronization circuit which provides a control signal that has been synchronized to the oscillator circuit to activate the selectable delay circuit to change the frequency of the clock signal. In some embodiments, a method includes generating a clock signal in an oscillator circuit, and synchronizing activation of a selectable delay circuit in the oscillator circuit to a local clock signal.
