NOTES
1.
The limit for frequency/temperature stability shall be referenced to the output frequency at 25 °C with Vc = any constant
value within the control voltage range.
2.
Unless otherwise specified, the limits are over the full operating temperature range and under specified load conditions.
3.
Unless otherwise specified, all measurements are in accordance with MIL-PRF-55310.
4.
Referenced to nominal output frequency. Up to 30 days after shipment (does not include Aging). Center tuning voltage is
defined as Vc = 2.5 volts.
5.
Slope of linear estimate (least squares) for 0 < Vc < 5V.
6.
Voltage values are with respect to network ground terminal.
7.
A standard CMOS load of 10 kOhm || 15 pF shall be used. See MIL-PRF-55310/26 for CMOS waveform measurement
definitions .
