Abstract

Described embodiments include a system, including clocked circuitry, an oscillator controller, and an oscillator, configured to output an output clock signal that clocks the clocked circuitry and is fed to the oscillator controller. The oscillator controller is configured to control the oscillator responsively to an output frequency of the output clock signal. The system further includes power-management circuitry, configured to cause the clocked circuitry to sleep by disabling the oscillator, and waking circuitry, configured to intermittently enable the oscillator such that the oscillator controller intermittently, while the clocked circuitry sleeps, causes the output frequency to converge to a target frequency by controlling the oscillator. Other embodiments are also described.
