Abstract
A system comprises a primary oscillator that provides a first signal having a first phase and a backup oscillator that provides a second signal having a second phase. The system also comprises trim logic coupled to the backup oscillator logic. Prior to failure of the primary oscillator, the trim logic adjusts the second phase to match the first phase. Upon failure of the primary oscillator, the second signal is used in lieu of the first signal.
