Notes: 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 25C. 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 tristated, 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) Output is AC coupled.
