Model IQXT-316-4 Model Issue number 1 Outline (mm) Frequency Parameters Frequency 25.0MHz Frequency Tolerance Tolerance Condition Frequency Stability Max 1.00ppm @ 25C 1C & VC=1.65V 0.25ppm Operating Temperature Range -5.00 to 85.00C Inservice Short-term Frequency Stability: 50 to 70C: 80ppb max 15 to 85C: 100ppb max -5 to 85C: 250ppb max Ageing: 20ppb max/day 200ppb max/month 1ppm max/year 2ppm max over 3yrs Temperature Rate of Change (maximum rate of change of temperature condition for guaranteed stability specifications): 1C/min max Acceleration Sensitivity (gamma vector of all 3 axes from 30 to 1500Hz): Typically 2ppb/G max Supply Voltage Variation (2% change @ 25C, measurement referenced to frequency observed @ nominal Vs): 10ppb typ Load Variation (2% change @ 25C, measurement referenced to frequency observed @ nominal load): 10ppb typ Reflow Variation (pre to post reflow F, measured after 1hr recovery @ 25C): 0.5ppm max Note: The characteristics of the oscillator may be temporarily affected by the processes of assembly and soldering. The in-service short term frequency stability specification applies after 48hrs continuous operation and after the first excursion over the temperature range. Nominal conditions apply unless otherwise stated. Electrical Parameters 3.3V 5% Supply Voltage Current Draw 3.500mA Absolute Maximum Ratings: Supply Voltage (Vs): -0.5V to 7V Control Voltage (VC): -0.5V to 9V All other inputs: -0.5V to Vs+0.5V Power Dissipation: 100mW max Junction Temperature: 150C max Note: Operating beyond these limits may result in change or permanent damage to the oscillator.

Logic '1' (60%Vs min) or no connection to pad 6 enables the oscillator output. Note: The tri-state control (enable) input pad has an internal 100k pull up resistor which allows it to be left unconnected if not used. When in tri-state mode, the output stage is disabled, but the oscillator and compensation circuit are still active (Current Consumption: 2mA typ).
