Abstract
A method and apparatus for mitigating electromagnetic noise in an electronic device. The method includes generating a trigger clock signal at a first frequency, and generating a second clock signal at a second frequency. The second frequency is higher than the first frequency. The method also includes receiving an input signal with a converter circuit, detecting an event based on the trigger clock signal, and predicting a time for a conversion of the input signal based on the detected event. The method further includes blanking the second clock signal for a predetermined period based on the predicted time for a conversion.
