ABSTRACT:
A method and apparatus for digitally synchronizing data units received from multiple asynchronous data sources which includes storing the data necessary to compensate for phase and frequency differences between the independently clocked asynchronous sources. The method includes the step of comparing the input queues for each of said data streams against a set of known threshold conditions, and generating the composite output upon satisfaction of the threshold conditions. This method allows data from asynchronous data sources to be properly interleaved without implementation of complex phase or frequency compensation techniques, and without a large amount of data storage for buffering the input data. Furthermore, in its preferred embodiment, this invention allows the implementation of a fixed rate output clock, which greatly simplifies the design over the prior art.
