Input (EXTAL) Jitter Requirements
4.5 Input (EXTAL) Jitter Requirements
The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow
(that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is
fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase
and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
