specified peak-to-peak jitter value.
Skew is measured between outputs of the same bank under identical transitions.
Skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the respective inputs.
Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
= 2.5V ±5% or 3.3V ±10%; R
