Classification: CPC H  G | IPC G  H

Claim 17:
18. A method for operation a system on a chip (SoC), the method comprising:
producing, based on an oscillator signal at a first frequency, a first clock signal at the first frequency;
producing, based on the oscillator signal, a second clock signal at a second frequency being a division of the first frequency by an integer greater than 1;
selectively, based on a scaling configuration signal:
providing the first clock signal as a first output clock signal when the scaling configuration signal has a first value; or
providing the second clock signal as the first output clock signal when the scaling configuration signal has a second value;

producing a frequency indication signal indicating, in combination with the first output clock signal, a start of a new clock period of the second clock signal; and
producing, by a second clock divider, a second output clock signal at a third frequency, the second output clock signal being based on the first output clock signal and the frequency indication signal, the third frequency being a division of the second frequency by an integer greater than or equal to 1.
