What is the difference between Frequency Stability and Frequency Tolerance?
This is in reference to Oscillators.
The Frequency tolerance is the allowable deviation from the specified frequency at a specific temperature, usually at 25c.
Frequency Stability refers to the deviation from the nominal frequency at 25c over the rated temperature range.
Example of Percentage vs PPM
.01 % = 100 PPM
.005% = 50 PPM
.001 % = 10 PPM
