TCVCXO Specification Part No. + Packaging: LFTVXO070185Cutt Customer Part: Description The IQXT-260-16 employs an analogue ASIC for the oscillator and a high-order temperature compensation circuit in a 2.5 x 2.0mm size package. Model IQXT-260-16 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 0.7ppm max over 1yr 25C Frequency Stability: TA varied over operating temperature range, measurement referenced to frequency observed with Fref=(Fmax+Fmin)/2, Vs=2.85V, VC=1.4V and load=10k//10pF. Outline (mm) Frequency Slope (minimum of one frequency reading every 2C and VC=1.4V): -10C to 60C: 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): 1.6ppb/sec max Frequency Slope (minimum of one frequency reading every 2C and VC=1.4V): -30C to 85C: 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): 1.6ppb/sec max Note: Frequency Drift rate is calculated from the equation ppb/s=C/s x ppb/C. 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 Pb-Free Reflow (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): 0.1ppm max Load Variation (10% change 25C): 0.2ppm max Reflow Variation (after two consecutive reflows as per profile 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.
