Oscillators - Frequency Stability Vs Frequency Tolerance


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
