Abstract
An apparatus and method for synchronizing and tracking an input data stream and for generating a synchronous clock therefrom, comprising means for generating a plurality of clock signals oscillating at substantially the same frequency, but with different phases; a plurality of delay lines having a common data input for receiving said input data stream, each delay line having multiple delay elements connected in series and having a common clock input for receiving one of said clock signals for clocking data of said data stream along said delay line in a direction away from said common data input; means for detecting which of said plurality of delay lines said data from said data stream is propagating therein; and means for generating the synchronous clock based on one of said clock signals that clocks the delay line that data from said data stream is propagating therein.
