Abstract:
1. An apparatus for facilitating the alignment of non-synchronous input data streams received in the apparatus, the apparatus comprising: an analog to digital converter arrangement for digitizing the plurality of input data streams into a plurality of sequences of samples; and a synchronization processing arrangement comprising a processing chain for each data stream; wherein each processing chain comprises: an alignment pulse generator for generating alignment pulses for the sequence of the plurality of sequences of samples corresponding to the processing chain, and a first-in-first-out (FIFO) register arrangement for arranging the sequence of samples with respect to the alignment pulses for the sequence and for synchronizing the delivery of said plurality of sequences of samples to a common processor with respect to the respective alignment pulses; and a reference alignment pulse generator, the reference alignment pulse generator configured to generate and transmit reference alignment pulses to the FIFO register arrangement of said processing chains, each FIFO register arrangement configured to output a sequence of samples in an output stream to the common processor such that frame delineator data in the output stream coincide with the receipt of the reference alignment pulses in the FIFO register arrangement.
