11. Random jitter is measured with a K28.7 pattern, measured at ≤f MAX .
12. Deterministic jitter is measured at 2.5Gbps with both K28.5 and 2 23 –1 PRBS pattern.
13. Cycle-to-cycle jitter definition: The variation period between adjacent cycles over a random sample of adjacent cycle pairs. t JITTER_CC = T n –
14. Total jitter definition: with an ideal clock input frequency of ≤ f MAX (device), no more than one output edge in 10 12 output edges will deviate by
15. Integrated over the range of 12kHz to 20MHz.

High-frequency AC parameters are guaranteed by design and characterization.
Within device skew is measured between two different outputs under identical input transitions.
Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and no skew at the edges at the respective
inputs.
