Differential AC Timing Waveforms
Output Propagation and Skew Waveforms
NOTE 1: Pulse skew is calculated using the following expression:
tsk(p) =
Note that the tp
NOTE 2: AC propagation measurements should not be taken within the first 100 cycles of startup.
Differential Gate Disabled/Endable Showing Runt Pulse Generation
NOTE 1: As shown, it is possible to generate runt pulses on gate disable and enable of the outputs. It is the user’s responsibility to time
the G signal to avoid this problem.
