The maximum value for PLL enabled is given for minimum V
The indicated duty cycle is for the specified maximum frequency for which a part is rated. The minimum clock high or low
time required for correction operation, however, remains the same at lower operating frequencies; therefore, when a lower
clock frequency is used, the signal symmetry may vary from the specified duty cycle as long as the minimum high time and
low time requirements are met.
Periodically sampled and not 100% tested.
The skew is not guaranteed for any other MF value.
