Abstract:
Through the use of a multi-step sweep, the present invention is capable of increasing the speed and improving the error resistance of a signal alignment. In a specific embodiment of the invention, a method for the signal alignment of a target signal and an adjustable signal is disclosed. The target signal is sampled using three or more phase shifted versions of the adjustable signal to obtain a group of target signal state values. Next, through reference to the group of target signal state values it is determined that an edge of the target signal lies between a first phase shifted version and a second consecutive phase shifted version. In response, the first phase shifted version is selected as the starting point for a second sweep. During the second sweep, the phase of the first phase shifted version is sequentially adjusted in relatively small incremental steps to minimize the phase difference relative to the target signal.
