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).
Output voltage: At designated TTL load (see table I).
Logic 1: 2.4 V dc, minimum.
Logic 0: 0.5 V dc, maximum.
Rise and fall times: See table I.
Duty cycle: 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 shall be referenced to
the frequency measured at +23
°C ±1°C (f
ref
) instead of to the nominal frequency (f
nom
).
