Notes:
7.
High-frequency AC-parameters are guaranteed by design and characterization.
8.
Output-to-output skew is measured between two different outputs under identical transitions.
9.
Part-to-part 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.
10. Random Jitter is measured with a K28.7 pattern, measured at ≤ fMAX.
11. Deterministic Jitter is measured with both K28.5 and 2
23-1 PRBS pattern, measured at ≤ fMAX.
12. Cycle-to-cycle jitter definition: The variation of periods between adjacent cycles, Tn – Tn-1 where T is the time between rising edges of the
output signal.
13. Total Jitter definition: With an ideal clock input of frequency <fMAX, no more than one output edge in 10
12 output edges will deviate by
more than the specified peak-to-peak jitter value.
14. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each
other at the inputs.
