Electrical Specifications
20.12 Trimmed Accuracy of the Internal Clock Generator
The unadjusted frequency of the low-frequency base clock (IBASE), when the comparators in the
frequency comparator indicate zero error, can vary as much as ±25% due to process, temperature, and
voltage. The trimming capability exists to compensate for process effects. The remaining variation in
frequency is due to temperature, voltage, and change in target frequency (multiply register setting). These
effects are designed to be minimal, however variation does occur. Better performance is seen at 3 V and
lower settings of N.
