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) 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 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 10 KHz) 15uV p-p, Voltage Noise Density = 50nV/square root of Hz, Temperature Coefficient < 5ppm per degree C. 5) 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). 6) Additional pull ranges are available; please contact the factory for additional information. 7) Output is AC coupled.
