jitter (RJ). The worst-case maximum input SJ = 0.5 ns peak-to-peak and the RJ = 0.15 ns peak-to-peak per ANSI T1.646a standard. Since the
random jitter contribution is very small and difficult to produce exactly, only the maximum systematic jitter is produced and used for testing
the receiver. The corresponding receiver test window time-width must meet the requirement of 0.31 ns or larger. This worst-case test
window time-width results from the following jitter equation:
Minimum Test Window Time-Width = Baud Interval - Tx SJ max. - Rx SJ max. - Rx RJ max.
Respectively, Minimum Test Window Time-Width = 1.608 ns - 0.50 ns - 0.30 ns - 0.48 ns = 0.328 ns.
This is a test method that is within practical test error of the worst-case 0.31 ns limit.
