Dynamic clock control to reduce radio interference in digital equipment

A digital apparatus that comprises:

• a clock module configured to provide a clock signal;
• a wireless module that receives RF interference from the digital apparatus;
• and
• a control module configured to adjust the clock module to determine which of multiple clock signal frequencies minimizes RF interference in one or more selected frequency regions of interest.

A device that comprises:

• a clock source that provides a clock signal at a programmable frequency;
• a wireless module that receives RF interference directly or indirectly caused by the clock signal;
• and
• a control module that sets the programmable frequency of the clock signal so as to move at least some of the RF interference outside a frequency region of interest without stopping the clock signal altogether.

A method of reducing RF interference in digital equipment, the method comprising:

• providing a clock signal at an initial clock rate;
• identifying a frequency region in which to reduce RF interference;
• and
• adjusting the clock signal to a different, nonzero clock rate that reduces RF interference in the identified frequency region.

A method of reducing RF interference in a digital system, the method comprising:

• configuring the digital system to operate in an initial configuration;
• identifying a frequency region in which to reduce RF interference;
• and
• automatically reconfiguring the digital system in a manner that reduces RF interference in the identified frequency region.
