1. All frequencies, voltages, temperature ranges and enable/disable options may not be

available. Contact factory.

2. Total Tolerance = Calibration Tolerance + Frequency Stability over temperature.

3. Shock survival applies at -55ºC to +125ºC.

4. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing available.

Note: All parameters are measured at ambient temperature with a 10 M

Ω, 15 pF load.

5. Expected life at 200ºC is in excess of 1,500 hours.

ENABLE/DISABLE OPTIONS (E/N)

Statek offers two enable/disable options: E and N. The E-

version has a Tri-State output and stops oscillating internally

when the output is put into the high Z state. The N-version

does not have PIN 1 connected internally and so has no

enable/disable capability. The following table describes the

Enable/Disable option E.
