NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for general information only.
3. Unless otherwise specified, tolerances are ±.005 (0.13 mm) for three place decimals and ±.02 (0.5 mm) for
two place decimals.
4. All pins with NC function may be connected internally and are not to be used as external tie points or
connections.
5. Color dot or square corner shall be used to indicate pin number 1.
6. ESD indicator, open triangle, shall be marked anywhere on the top of the oscillator.

Logic 1:
Logic 0: See table I.
Rise and fall times: See table I.
Duty cycle: See table I.
Initial accuracy at +23C
1C
(up to 30 days after shipment):
15
ppm.
Initial frequency-temperature accuracy (one-half temperature cycle): Verification applicable. 1/
Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23C
1C,
immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments
over the specified operating temperature range. 1/
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 +23C
1C
(f
ref
) instead of to the nominal frequency (f
nom
).
