Notes:
8. High-frequency AC-parameters are guaranteed by design and characterization.
9. Propagation delay is a function of rise and fall time at IN. See “Operation Characteristics” for more details.
10. Output-to-output skew is measured between two different outputs under identical transitions.
11. 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
12. Random jitter is measured with a K28.7 character pattern, measured at <f
13. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each other at the
