The period of time during which the data must be valid in order for you
to capture it correctly. Sampling window is the sum of the setup time,
hold time, and jitter. The window of t
in the sampling window.
SW = TUI – TCCS – (2 × RSKM)
RSKM is defined by the total margin left after accounting for the
sampling window and TCCS.
RSKM = (TUI – SW – TCCS) / 2
