Abstract
A clock circuit comprises an analog clock element, a digital clock element, and a controller. The analog clock element is configured to generate an oscillating output. The digital clock element is configured to generate a digital clock output. The controller is configured to switch between the analog clock element and the digital clock element. The oscillating output and the digital clock output have substantially equivalent frequencies. Switching from the analog clock element to the digital clock element reduces the effects of electromagnetic radiation on an output of the clock circuit.
