    Notes:
    1.3) Initial calibration @ 25C. OCVCXO model Vc = 1.50 Vdc.
    2.3) Frequency stability vs. Change in temperature, referenced to 25C.
    3.3) Frequency stability per 5% change in supply voltage.
    4.3) At the time of shipment after 48 hours of operation.
    5.3) Inclusive of calibration, operating temperature range, supply voltage change,
    shock and vibration 20 years aging,
    models Vc=1.5V.
    6.3) Typical phase noise, results will vary depending on center frequency. The phase
    noise shown are typical for 20 MHz.
    7.3) Measured @ 25C, within 5 minutes, the unit will be within +/-0.1ppm of its reference
    frequency, measured after 30 minutes of continuous operation at a stable 25C.
    8.3)
    models pullability referenced to Fo @ 25°C, Positive Transfer
