What causes jitter?

There are several causes of jitter, some of there are: System phenomena, such as cross-talk from radiated or conducted signals, dispersion effects, and impedence mismatches. Data-dependent phenomena, due to the pattern of data in the bitstream data. This can result in inter-symbol interference, duty-cycle distortion, and pseudorandom periodicity in the bitstream. Random-noise phenomena, caused by […]
