Notes
31. These parameters are extrapolated from the input timing parameters (t_CYC/2 - 250 ps, where 250 ps is the internal jitter). These parameters are only guaranteed
by design and are not tested in production.
32. t_CHZ, t_CLZ, are specified with a load capacitance of 5 pF as in (b) of AC Test Loads and Waveforms. Transition is measured ± 100 mV from steady-state voltage.
33. At any voltage and temperature t_CHZ is less than t_CLZ and t_CHZ less than t_CO.
