MIL-PRF-55310/18D REQUIREMENTS: Interface and physical dimensions: See figure 1. Mounting: See figure 1. Terminals: See figure 1. Seal: Hermetic in accordance with MIL-PRF-55310, maximum leakage rate 5 x 10 atm cc/s. Weight: 0.5 ounce, maximum. * Oscillator: Class 2 (see 1.2.3 of 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: 10 kilohms 5 percent shunted by 15 pF 5 percent capacitor for CMOS compatible square. Output waveform: Symmetrical square wave. Output voltage: At designated CMOS load. Logic 1: See table I. Logic 0: See table I. Rise and fall times: See table I. Duty cycle: 40 to 60 percent duty cycle. 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). 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 +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 frequencytemperature 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).
