MIL-PRF-55310/14H
REQUIREMENTS:
Interface and physical dimensions: See figure 1.
Mounting: See figure 1.
Terminals: See figure 1.
Weight: 0.5 ounce, maximum.
Oscillator: Class 2 or any class 1 or class 3 oscillator meeting all class 2 requirements and verification tests
specified herein and in MIL-PRF-55310.
Calibration: Manufacturer calibrated.
Screening: In accordance with MIL-PRF-55310, product level B or S, as applicable.
Temperature:
Operating: See table I.
Storage: -62C to +125C.
Oscillator load: 1 to 10 standard TTL loads. A TTL unit load is defined as: 1.6 mA sink, 0.04 mA source
and 2 pF capacitance.
Output waveform: Symmetrical square wave.
Supply voltage: See table I.
Input current: At designated supply voltage (see table I).
Output frequency: Frequency as designated at time of acquisition (see table I).
Output voltage: At designated TTL load (see table I).
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 (fref) instead of to the nominal frequency (fnom).
