Abstract
A stable and flexible synchronization system and method are disclosed. The method includes selecting to receive an external clock signal, detecting a difference between an internal clock signal and the selected external clock signal and generating a control signal representing the difference; determining if the control signal has a first value that is within a predetermined range; calculating a second value representing an absolute value of a difference between a current value of the control signal and a previous value of the control signal; determining if the value is less than a third value; resetting the output signal upon receipt of an edge of said selected external clock signal; determining if a timing difference between the output signal and the selected clock signal is substantially zero; and issuing a signal indicative of synchronization.
