TCXO Specification IQXT-225 ISSUE 1 February 2018 Description IQXT-225 is a 2.0 x 1.6mm SMD Temperature Compensated Crystal Oscillator (TCXO) in a hermetically sealed package with E/D on pad 1 for low power operation. Developed frequencies: 16.368, 16.369, 19.2, 26.0, 33.6 and 38.4MHz Frequency Parameters Frequency 16.368MHz to 38.4MHz Frequency Tolerance Max 1.50ppm 0.50ppm Frequency Stability Ageing 1ppm max per year 25C 2C Frequency Tolerance: 25C 2C referred to nominal frequency before reflow soldering. Supply Voltage Variation ( 5% change): 0.1ppm max Load Variation ( 10% change): 0.1ppm max Outline (mm) Reflow Variation (at 25C 2C referred to frequency before reflow): 1ppm max, 24 hrs after reflow. Electrical Parameters 1.2V 5% Supply Voltage Absolute Maximum Ratings: Supply Voltage: -0.6V to 4.6V E/D Control Voltage: -0.6V to Vs+0.6V (4.6V max) Operating Temperature Ranges -30 to 85C Output Details Output Compatibility Clipped Sine Drive Capability 10k//10pF 10% Output: DC coupled Note: a 1000pF DC-cut capacitor is to be connected in the output line of the TCXO. Output Level: 0.8V pk-pk min Start Up Time: Vout 90% of V pk-pk: 2ms max Start Up Time (within 0.5ppm): 2ms max Output Control Enable/Disable (pad 1): Logic 1 (80%Vs min) or no connection to pad 1 enables the oscillator output. Logic 0 (20%Vs max) to pad 1 disables the oscillator output, the output goes to a high impedance state. Disable current in E/D mode: 3A max Noise Parameters Phase Noise (typ): -135dBc/Hz 1kHz Environmental Parameters Storage Temperature Range: -40 to 85C Manufacturing Details RoHS Terminations NiAu RoHS Reflow +250C 10C for 10 sec max 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 12 Feb 18 11:46 using Model Data Sheet V1.2550 Page 1 of 2TCXO Specification IQXT-225 Ordering Information *Minimum info required Frequency* Model* Output Frequency Stability (over operating temperature range)* Operating Temperature Range* Supply Voltage Example 26.0MHz IQXT-225-12 Clipped Sine 0.5ppm 30 to 85C 1.2V Compliance RoHS Status (2011/65/EU) Compliant REACh Status Compliant MSL Rating (JDEC-STD-033): Not Applicable Packaging Details Pack Style: Reel Tape & reel in accordance with EIA-481-D Pack Size: 3,000 Pack Style: Cutt Cut tape Pack Size: 100 Electrical Specification - maximum limiting values 1.2V 5% Frequency Frequency Stability Current Rise and Fall Duty Cycle Temperature Min Max (Min) Draw Time Range % C ppm mA ns 16.368MHz 38.4MHz -30 to 85 0.5 1.7 - - This document was correct at the time of printing please contact your local sales office for the latest version.
