The frequency tolerance of a crystal or oscillator defined as the initial deviation of a crystal or oscillator frequency when measured at 25°C. The stability over the defined operating temperature range is defined as the Frequency Deviation compared to the measured frequency at 25°C. Tolerance and stability are typically expressed as parts per million and sometimes as a percentage of the frequency.
