Approved for public release; distribution is unlimited.
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 x 10 atm cc/s. Weight: 0.5 ounce, maximum. * Oscillator: Class 2 (see of MIL-PRF-55310). Calibration: Manufacturer calibrated. * Screening: In accordance with MIL-PRF-55310, product level S, as applicable. Temperature: Operating: See table I. Storage: to +125°C. Oscillator load: 10 kilohms ±5 percent shunted 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: 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 +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 frequencytemperature accuracy (one-half temperature cycle)' shall apply except that frequency measurements shall be referenced to the frequency measured +23°C ±1°C (fref) instead of to the nominal frequency (fnom).
Dash number Output frequency range Supply voltage ±10% Maximum Input current at maximum supply voltage 1/ mA Output voltage Rise and fall times (max) Initial accuracy ppm +23°C ±1°C Frequency aging ppm/year after 30 days Frequency-temperature tolerance (ppm) +70°C C
1/ Maximum input current for no load condition. Actual configuration of CMOS loads must be added to determine power supply requirements.
