LFTCXO070180Cutt IQD

TCXO Specification Part No. + Packaging: LFTCXO070180Cutt Description Outline (mm) The IQXT-275-1 employs an analogue IC for the oscillator and temperature compensation. The crystal is surface mounted on top of the ceramic IC carrier. The segregation of the crystal from the oscillator further improves the reliability of the product. Model IQXT-275-1 Model Issue number 1 Frequency Parameters Frequency 19.20MHz Frequency Tolerance 1.00ppm Tolerance Condition 25C 2C Frequency Stability 0.50ppm Operating Temperature Range -30.00 to 85.00C Ageing 1ppm max over 1yr 25C Frequency Stability: TA varied over operating temperature range, measurement referenced to frequency observed with Fref=(Fmax+Fmin)/2, Vs=1.8V and load=10k//10pF. Frequency Slope (minimum of one frequency reading every 2C): -10C to 60C: 0.05ppm/C max -30C to 85C: 0.1ppm/C 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 range): 50ppb/C max (Note: Discard the first 0.5C interval of each heating and cooling cycle.) 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 25C): 0.2ppm max Load Variation (10% change 25C): 0.2ppm max Reflow Variation (after two consecutive reflows as per profile Pb-Free Reflow shown and 1hr recovery 25C): 1ppm max Note: Parts should be shielded from drafts causing unexpected thermal gradients. Temperature changes due to ambient air currents can lead to short term frequency drift. Electrical Parameters 1.8V 5% Supply Voltage Current Draw 2.00mA Supply Current ( TA=25C, Vs max and load=10k//10pF): 2mA max Output Details Output Compatability Clipped Sine Drive Capability 10k//10pF 10% Output Voltage Level ( TA=25C, Vs min and load=10k//10pF): 0.8V pk-pk min Output: DC coupled Note: AC-coupled output requires an external capacitor, 1nF recommended.
