1. Guaranteed by design.

2. The maximum frequency is defined with the following conditions:



(tr+tf) ≤ 2/3 T

Skew ≤ 1/20 T



45%<Duty cycle<55%

3. The fall and rise times are defined between 90% and 10% and between 10% and 90% of the output waveform, respectively.

4. Compensation system enabled.
