ABSTRACT:
The invention discloses a method and system for synchronizing external data to an internal timing signal. External data is received in conjunction with a clock input. The clock input has first set of values and a second set of values. The clock input is compared to an internal timing signal having a frequency that is a multiple of the clock input. The internal timing signal is shifted by adjusting the count of a counter if the clock input transitions from the first set of values to the second set of values within a predetermined range of the internal timing signal.
