Adaptive spread-spectrum clocking


Technologies are described herein for adaptive spread-spectrum clocking to limit interference in a target band. Interference in the target band may be reduced by changing the frequency of the clock signal at a higher modulation rate for clock frequencies that interfere with, or are correlated to, the target band and changing the frequency of the clock signal at a lower modulation rate for the clock frequencies that are not correlated to the target band..
