Notes:
1. Frequency referenced to Fo.
2. Frequency stability vs. change in temperature. [±(Fmax - Fmin)/2.Fo].
3. Inclusive of frequency stability vs. change in temperature , supply voltage change and aging over a 24 hour period.
4. Referenced to 15 pF.
5. Inclusive of calibration@25°C, frequency vs. change in temperature, change in supply voltage(±5%), load change(±5%) and 20 years aging.
6. Output is enabled with no connection on pad 8.
7 Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this data sheet, it is required that the circuit connected to this TCXO output must have
the equivalent input capacitance that is specified by the nominal load capacitance. Deviations from the nominal load capacitance will have a graduated effect on the stability of approximately
20 ppb per pF load difference.
