Phase Lock Loop (PLL) Characteristics
Measured at 50 percent of the input transition.
The maximum value for PLL enabled is given for minimum VCO frequency (see Table 2-4) and maximum MF.
Periodically sampled and not 100 percent tested.
The maximum value for PLL enabled is given for minimum VCO frequency and maximum DF.
The skew is not guaranteed for any other MF value.
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.
