Notes:
7. High-frequency AC-parameters are guaranteed by design and characterization.
8. Propagation delay is measured with input t_r, t_f ≤ 300ps (20% to 80%) and V_IL ≥ 800mV. The propagation delay is function of the rise and
fall times at IN. See “Typical Operating Characteristics” for details.
9. Set-up and hold times apply to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous
applications, set-up and hold do not apply.
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 respective inputs.
12. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each
other at the inputs.
