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 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 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 tri-

stated, the output stage is disabled but the oscillator and compensation circuit

are still active (current consumption < 1mA).

6) Additional pull ranges are available; please contact the factory for additional

information.

7) Output is AC coupled.
