A device may generate a clock signal using spread-spectrum clocking. The spread-spectrum clocking may modulate a frequency of the clock signal to produce a plurality of frequencies for the clock signal during a modulation cycle. The device may receive an instruction to disable the spread-spectrum clocking, and may disable the spread spectrum clocking at the end of the modulation cycle.

Disabling spread-spectrum clock signal generation

A method and a phase-locked loop (PLL) for generating output clock signals with desired frequencies are described. The PLL is equipped with a ramp generator that increments or decrements a feedback divider value before providing it to a modulator. The modulator modulates the feedback divider value and provides the modulated value to a feedback divider of the PLL for performing frequency division.
