Propagation delay is a function of the rise and fall times at IN. See “Typical Operating Characteristics” for details.

10. Output-to-output skew is measured between two different outputs under identical conditions.

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 respective inputs.

than the specified peak-to-peak jitter value.

15. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each

other at the inputs.
