TCXO Specification Part No. + Packaging: LFTCXO070037Cutt Customer Part: Description The IQXT-270-4 temperature compensated crystal oscillator (TCXO) employs an analogue ASIC for the oscillator and a high order temperature compensation circuit in a 2.0 x 1.6mm size package. Model IQXT-270-4 Model Issue number 1 Frequency Parameters Frequency 19.20MHz Frequency Tolerance 1.00ppm 0.50ppm Frequency Stability Operating Temperature Range -30.00 to 85.00C Ageing 0.7ppm max per year at 25C Frequency Tolerance: Offset from nominal frequency measured at 25C 2C. Reflow Shift (two consecutive reflows as per profile after 1 hour relaxation at 25C): 1ppm max Outline (mm) Frequency Stability: Referenced to the midpoint between minimum and maximum frequency value over the specified temperature range (note 1). Frequency Slope (temperature range -10 to 60C. Tested to a minimum of one frequency reading every 2C - note 1): 0.05ppm/C max Frequency Drift (calculated from frequency slope with temperature varied at a maximum of 1.92C/min (0.032C/s) over -10C to 60C, Note 5): 1.6ppb/sec max Frequency Slope (temperature range -30C to 85C. Tested to a minimum of 1 frequency reading every 2C Note 1): 0.1ppm/C max Frequency Drift (calculated from frequency slope with temperature varied at a maximum of 0.96C/min (0.016C/s) over -30C to 85C, Note 5): 1.6ppb/sec max Small thermal cycle frequency slope (measured at 0.5C intervals over any 5C heating and 5C cooling cycle, at a minimum rate of 1C/minute within the operating temperature Pb-Free Reflow range, Note 6): 50ppb/C max Small thermal cycle hysteresis (difference in frequency measurements over any 5C heating and 5C cooling cycle, at a minimum rate of 1C/minute within the operating temperature range): 50ppb pk-pk max Supply Voltage Variation (5% change at 25C): 0.1ppm max Load Variation (10% change at 25C - note 2): 0.2ppm max Electrical Parameters 1.8V 5% Supply Voltage Current Draw 1.500mA Supply Current (at Vs max - note 2): 1.5mA max Output Details Output Compatibility Clipped Sine Drive Capability 10k//10pF 10% Output Voltage Level (at Vs min - note 2): 0.8V pk-pk min Output: DC coupled (note 3) 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 22:24 using Part Data Sheet V1.0018 Page 1 of 2TCXO Specification Part No. + Packaging: LFTCXO070037Cutt Customer Part: Noise Parameters Phase Noise at 25C (typical): -64dBc/Hz 1Hz -93dBc/Hz 10Hz -118dBc/Hz 100Hz -137dBc/Hz 1kHz -149dBc/Hz 10kHz -151dBc/Hz 100kHz Phase Noise at 25C (max): -57dBc/Hz 1Hz -86dBc/Hz 10Hz -111dBc/Hz 100Hz -133dBc/Hz 1kHz -144dBc/Hz 10kHz -148dBc/Hz 100kHz Environmental Parameters Shock: MIL-STD-202 M213 (note 4): Half sine-wave acceleration of 3000G peak amplitude, duration 0.3ms, velocity 12.3ft/s. Moisture Resistance: MIL-STD-202 M106g (note 4): 1000 hours at 85C, 85% relative humidity. Biased. Thermal Cycling: JESD22 Method JA-104C (note 4): 1000 temperature cycles, where each cycle consists of a 25 minutes soak time at -40C followed by a 25 minute soak time at 85C, with a 60 second maximum transition time between temperatures. Air to air transition. Vibration: JESD22-B103-B (also see note 4): 10G peak acceleration for 20 minutes 12 cycles in each of the 3 orientations, swept from 10-2000Hz. Storage Temperature Range: -40 to 85C Manufacturing Details Maximum Process Temperature: 260C (40secs max) Note 1: Parts should be shielded from drafts causing unexpected thermal gradients. Temperature changes due to ambient air currents can lead to short term frequency drift. Note 2: Specified for the load stated in Output Details above, at 25C. Note 3: External AC coupling capacitor required 1nF or greater recommended. Note 4: Frequency shift of 1ppm max after environmental conditions. Note 5: Frequency drift rate is calculated from the equation ppb/s=C/s x ppb/C Note 6: Discard the first 0.5C interval of each heating and cooling cycle Compliance RoHS Status (2015/863/EU) Compliant REACh Status Compliant MSL Rating (JDEC-STD-033): Not Applicable Packaging Details Pack Style: Cutt In tape, cut from a reel Pack Size: 100 Alternative packing option available 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 22:24 using Part Data Sheet V1.0018 Page 2 of 2
