While Deterministic Jitter (DJ) is generally agreed to be peak limited, what is less clear is how rapidly its PDF decreases near that limit, especially when the DJ is due to crosstalk.
This paper addresses this and related questions by considering a class of responses which are similar to real system responses but are described by closed form equations. These responses can therefore be evaluated precisely at arbitrary times, allowing the tails of the jitter distribution to be explored in detail. The result is a clearer understanding of when the tails of a DJ PDF can resemble a Gaussian.
