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) 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/sqrt Hz, Temperature Coefficient < 5ppm/°C.
4) Leave Pad 8 unconnected if enable / disable function is not required. When tri-
stated, the output stage is disabled but the oscillator and compensation circuit
are still active (current consumption < 1 mA).
5) Additional pull ranges are available; please contact the factory for additional
information.
6) Attention: To achieve the frequency stability specified 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.
7) Output is AC coupled.
