This patent disclosure presents circuits, systems and methods to extract the clock signal from a data stream. This new invention is far better than the current technologies in the range of frequency locking and tracking. Since the new data clock recovery system is built by digital circuits only, it can be implemented inside an IC easily. This invention is especially helpful for high speed data communication products since the clock can be recovered at full data rate.

Title
Data clock recovery system using digital arrival-time detector
