Abstract
A system and method for filtering a jittered clock is disclosed. The filter of the present invention may check if a reference clock is received at a point in time within a pre-defined window of time. If the clock is received at a point in time within the window, the reference clock may be utilized as a reference for a system application such as a reference for a phase-locked loop. If the reference clock is not received at a point in time within the window, an interpolated clock representing an ideal received clock may be utilized. This may minimize the disturbance of system applications by blocking extreme deviations of the reference clock.
