Notes:
1) Frequency vs. temperature stability, Vc = 1.65V.
2) Inclusive of calibration, oper ating temperature range, suppl y voltage change, load
change, shock and vibration, 10 years aging, Vc = 1.65V.
3) After one minute of operation at 25
C, the unit will be within +/-0.5ppm of its final
stabilized frequency. The final stabilized frequency is t hat which is measured after 30
minutes of continuous operatio n at a stable 25
C ambient temperature.
4) Referenced to Fo @ 25
C
, Positive Transfer Character istic
5) Oscillator output is enabled with no connection on pin 3.
