US Patent 7500155 Average time extraction circuit for eliminating clock skew

The method involves detecting a first signal characterized by a periodically occurring first event, detecting a second signal characterized by a periodically occurring second event, and based on both the detected first and second signals, generating a third signal characterized by a periodically occurring third event. The method also involves automatically adjusting the phase of the third signal so that the periodically occurring third event occurs at a predetermined location between the first and second events of the first and second signals.
