RITOL ≥ Cable Skew (type, length) + Source Clock Jitter (cycle to cycle) (Note 11) + ISI (Inter-symbol interference) (Note 12) Cable Skew — typically 10 ps–40 ps per foot, media dependent

Please see National’s AN-1217 for more details.

Note 11: Cycle-to-cycle jitter is less than 100 ps (worse case estimate).

Note 12: ISI is dependent on interconnect length; may be zero.
