Note
1) TCXO: Initial calibration @ 25°C. Specifications at time of shipment after 48 hours of operation.
2) Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.
3) Inclusive of calibration @ 25°C, frequency vs. change in temperature, change in supply voltage (±5%), load change (±5%), reflow soldering process
and 20 years aging.
4) For best in application performance, careful selection of an external power source is critical. Select an external regulator that meets or exceeds to
following specifications regarding voltage regulation tolerance, initial accuracy, temperature coefficient, voltage noise, and low voltage noise density
Factory Test Conditions:
Initial Accuracy ±2mv, Noise (0.1Hz to 10 KHz) 15uV p-p, Voltage Noise Density = 50nV/srt Hz, Temperature Coefficient
< 5ppmºC.
5) Phase noise measurements Fo = 20 MHz, other frequencies may vary by 20log F/20MHz.
6) Typical start up time for the frequency range of 12.8 MHz to 25 MHz <330 us.
7) Additional pull ranges are available; please contact the factory for additional information.
8)
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 T CXO 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.
9) Output is AC coupled.
