PERFORMANCE SPECIFICATION SHEET

OSCILLATOR, CRYSTAL CONTROLLED, TYPE 1 (CRYSTAL OSCILLATOR (XO)),

40.0 kHz THROUGH 60.0 MHz, HERMETIC SEAL, SQUARE WAVE, TTL

This specification is approved for use by all Departments
and Agencies of the Department of Defense.

The requirements for acquiring the product described herein
shall consist of this specification sheet and MIL-PRF-55310.

NOTES:

1. Dimensions are in inches.

2. Metric equivalents are given for general information only.

3. Unless otherwise specified, toler anc es are ±.005 (0.13 mm) for three place decimals and ±.02 (0.5 mm) for two
place decimals.

4. All pads with NC function may be connected internally and are not to be used as external tie points or
connectors.

Supply voltage: 5.0 V dc ±10 percent.
Input current: At designated supply voltage (see table I).
Output frequency: Frequency as designated at time of acquisition (see table I).
Initial accuracy at reference temperature (up to 30 days after shipment): See table I.
Initial frequency-temperature accuracy (one-half temperature cycle): Verification applicable. 1/
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/

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 sh all be refer en ced to
the frequency measured at +23°C ±1°C (f

) instead of to the nominal frequency (f
