Bounded Uncorrelated Jitter
Similar to random jitter, bounded uncorrelated jitter (BUJ) has also a Gaussian
distribution, but this distribution is cut (bounded) at both sides.
This kind of jitter can be caused, for example, by crosstalk on a parallel bus or by
intersymbol interference of random or long pseudo random binary bit sequences.
To simulate bounded uncorrelated jitter for jitter tolerance tests, it can be
generated from a filtered (frequency-limited) PRBS.
Periodic Jitter
Periodic jitter (PJ) is generally picked up from other periodic sources.
Rectangular jitter may be caused, for example, by a switching power supply. It has
a distribution as shown below.
