TCVCXO Specification Part No. + Packaging: LFTVXO076348Reel Customer Part: Description Outline (mm) The IQXT-316-6 uses ASIC technology and is designed to meet the short and medium term stability requirements of packet network synchronisation for Small Cells. Model IQXT-316-6 Model Issue number 1 Frequency Parameters Frequency 40.0MHz Frequency Tolerance 1.00ppm Tolerance Condition 25C 1C & VC=1.65V Frequency Stability 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): 25ppb typ Load Variation (2% change 25C, measurement referenced to frequency observed nominal load): 25ppb 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 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 4.500mA 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). Output Enable Time: 100s max Noise Parameters Phase Noise 25C (typ): -60dBc/Hz 1Hz -90dBc/Hz 10Hz -118dBc/Hz 100Hz -138dBc/Hz 1kHz -152dBc/Hz 10kHz -156dBc/Hz 100kHz -158dBc/Hz 1MHz Phase Jitter (12kHz to 5MHz): 290fs RMS typ Sales Office Contact Details: UK: +44 (0)1460 270200 France: 0800 901 383 Email: info iqdfrequencyproducts.com Germany: 0800 1808 443 USA: +1.760.318.2824 Web: www.iqdfrequencyproducts.com Printed on 4 Aug 21 23:53 using Part Data Sheet V1.0018 Page 2 of 3
