Abstract

This paper presents a synchronization signal recovery, both with and without spread spectrum clocking, by post-processing of waveform acquisitions in high-speed interface transmission lines. A count random process model was used for derivation the algorithm of clock recovery from the encoded data signals. The dependence of the reconstructed synchronization signal phase on random intervals between sign changes is determined. A signal flow algorithm for converting a high-speed interface signal, measured by a digital oscilloscope, into a synchronization signal is developed. The effectiveness of the developed algorithm of synchronization signal recovery for frequency modulated measured data of high-speed interface is demonstrated.
