Symbol Phase Synchronizers

Abstract

This work study four symbol synchronizers namely the analog, hybrid, combinational and sequential. These four synchronizers will be tested with three differentinput sequences (P1, P2 and P7). P1=21 (1one-1zero 1-0) isdeterministic, P2=22 (2ones-2zeros 11-00) is deterministicand P7=27-1 (1 ... 0) is pseudo - random. The objective is to study the four synchronizers and toevaluate their jitter UI-RMS (Unit Interval-Root Mean Squared) versus input SNR (Signal- Noise Ratio), when the input sequence changes between P1, P2 and P7.
