      The maximum value for PLL enabled is given for minimum V
      CO
      and maximum MF.
      3
      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 correct 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.

      The maximum value for PLL enabled is given for minimum VCO and maximum DF.
