TCXO: Initial calibration @ 25°C. Specifications at time of shipment after 48 hours of operation.
Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.
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.
For best in application performance, careful selection of an external power source is critical. Select an external regulator that meets or exceeds to the 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 10KHz) 15uV p-p, Voltage Noise Density = 50nV/ (Square root Hz), Temperature Coefficient <5ppm°C.
Additional pull ranges are available; please contact the factory for additional information.
Attention: To achieve optimal frequency stability, and in some cases to meet the specification stated on this datasheet, 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 20ppb per pF load difference.
Output is DC coupled.
