Notes:
1) Initial calibration @ 25
°C, Vc=1.4V.
2) Frequency stability, 0 to 70
°C, referenced to 25°C.
3) Frequency stability per 5% change in supply voltage.
4) At the time of shipment after 48 hours of operation.
5) Inclusive of operating temperature range, supply voltage change, load change, shock and
vibration, 10 years aging, Vc=1.4V.
6) Measured @ 25
°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference frequency,
measured after 30 minutes of continuous operation at a stable 25
°C
7) Referenced to Fo @ 25
°C, Positive Transfer Characteristic.
