Abstract
A first oscillator signal and a second oscillator signal are transmitted to a processing unit. The first oscillator signal has a finite frequency or phase offset relative to the second oscillator signal. A first clock signal that is derived from the first oscillator signal is selected as a primary clock to clock the processing unit. A second clock signal derived from the second oscillator signal is aligned to the first clock signal. If a fault is detected on the first clock signal, the second clock signal is selected as the primary clock to clock the processing unit. Upon being selected as the primary clock, the phase of the second is stretched by one fixed phase for one clock cycle.
