Abstract

Techniques, methods and system, for synchronization of sparse data signals are disclosed, comprising mixing a serial stream of sparse data signals with a serial stream of synchronization signals, to thereby add redundancy to the serial stream of sparse data signals and enable clock regeneration from a serial stream of mixed signals produced by said mixing, emulating the serial stream of synchronization signals by applying the clock regeneration to the serial stream of mixed signals, and generating a stream of parallel synchronization signals having a frequency of the serial stream of synchronization signals, deserializing the serial stream of mixed signals into a stream of parallel mixed signals having a data rate lower than a data rate of the serial signal streams, and demixing the stream of parallel synchronization signals with the stream of parallel mixed signals and thereby removing the redundancy introduced by the mixing into the sparse data signals and generating a parallel stream of demixed signals substantially synchronized with said synchronization signals.

a clock regeneration unit configured to operate on said serial stream of mixed signals;
a data speed convertor configured to convert said serial stream of mixed signals into a stream of parallel mixed signals;
and a demixer configured to remove the redundancy introduced by said mixer into said sparse data signals,
characterized in that
said serial stream of synchronization signals comprising a pseudo random binary sequence (PRBS), and said clock regeneration unit configured to determine a frequency of said serial stream of synchronization signals comprising said PRBS,
