TABLE I. Dash numbers and operating characteristics.
1/ Temperature range A applicable for product level B oscillators only.
2/ Maximum input current for no load condition.
3/ See
Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23°C ±1°C,
immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments over
the specified operating temperature range. 1/
Frequency-voltage tolerance: ±4 ppm maximum for a ±10 percent change in supply voltage. Measurements taken
at reference temperature and operating temperature range end points.
Frequency aging: Measurements shall be taken at +70°C ±0.2°C at intervals of not more than every 72 hours for
30 days minimum (Except one maximum interval of 96 hours per 30 days is permitted).
±
10 ppm per year, maximum.
±
1.5 ppm per 30 days.
±
3 ppm per 90 days.
1/ For the purpose of transitioning this device to
MIL-PRF-55310
, ‘Frequency stability versus temperature’ has been
renamed ‘Frequency-temperature tolerance’. The verification requirements of ‘initial frequency-temperature
accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall be referenced to the
frequency measured at +23°C ±1°C (f
ref
) instead of to the nominal frequency (f
nom
).
