MIL-PRF-55310/21G

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

/ 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
