Difference Between tODCV And tPWH / tPWL of RoboClock

Question: What is the difference between tODCV and tPWH /tPWL?

 

Answer:

ODCV is the deviation of the output from 50% duty cycle measured at 1.5V. t PWH /t PWL is the deviation measured at the corresponding high and low thresholds (t PWH is measured at 2.0V, t PWL is measured at 0.8V). The differences account for rise and fall time pulse-narrowing from the 50% point measurement.
