Notes

23.These parameters are extrapolated from the input timing parameters (tCYC/2 - 250 ps, where 250 ps is the internal jitter). These parameters are only guaranteed by design and are not tested in production.

24.tCHZ, tCLZ 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.

25.At any voltage and temperature tCHZ is less than tCLZ and tCHZ less than tCO.
