TCXO Specification Part No. + Packaging: LFTCXO070032Cutt Description The IQXT-260-10 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-260-10 Model Issue number 1 Frequency Parameters Frequency 26.0MHz Frequency Tolerance 1.00ppm Tolerance Condition 25C 2C Frequency Stability 0.50ppm Operating Temperature Range -40.00 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 Outline (mm) 2C over the operating temperature range): 0.1ppm/C max Static Temperature Hysteresis (frequency change after reciprocal temperature ramped over the operating range - frequency measured before and after 25C): 0.6ppm max Frequency Drift on Power Up: Drift Period 0.03 to 1.0 second: 500ppb/s max Drift Period 1.0 to 2.0 seconds: 40ppb/s max Drift Period 2.0 to 3.0 seconds: 2.5ppb/s 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. Electrical Parameters Pb-Free Reflow Supply Voltage 1.8V 5% Current Draw 1.50mA Supply Current ( TA=25C, Vs max and load=10k//10pF): 1.5mA max Output Details Clipped Sine Output Compatability Drive Capability 10k//10pF 10% Output Voltage Level ( TA=25C, Vs min and load=10k//10pF): 0.8V pk-pk min Start Up Time (amplitude within 90% of specified output level): 0.5ms max Start Up Time (frequency within 0.5ppm of steady state frequency): 1.5ms max Output: DC coupled Note: AC-coupled output requires an external capacitor, 1nF recommended. Output Control Power Down Mode: Logic 0 (10%Vs max) to pad 1 disables oscillator output. Logic 1 (90%Vs min) to pad 1 enables oscillator output.
