Notes:
1. Initial calibration @ 25°C, Vc = 2.0Vdc at time of shipment.
2. Frequency vs. temperature stability, absolute 0 to 70°C.
3. After Ten days of continuous operation.
4. Allen Variance: 1 second, 100 average. DAta is taken from the phase noise measurement.
5 Frequency vs. change in supply voltage, absolute 4.75 to 5.25 Vdc.
6 Frequency vs. change in load, absolute 12 pF to 18 pF.
7. Vcc = 5.0 Vdc @ 25°C.
8. Measured @ 25°C, within 5 minutes, referenced one hour after turn-on.
9. Positive slope.
