The device can be placed in power down mode through a single input pin. During standard operation, power consumption is minimised by operating down to a supply voltage of 1.8V. The IQXT-260's high stability, low power consumption, small footprint and powerful compensation method makes it a TCXO ideally suited for demanding GPS mobile applications. Applications: - GPS Smartphone PNS Consumer Communications - Wi-Fi - WiMax/W-LAN ## **Outline (mm) Pad 1 GND/NC** - Features: Frequency slope and perturbation specifications can be customised to the application requirement Excellent phase noise performance Standard temperature stability choices are Ā±0.5ppm, Ā±1ppm, Ā±1.5ppm and Ā±2.5ppm over wide temperature ranges ## **Frequency Parameters** - Frequency 10.0MHz to 52.0MHz Frequency Tolerance Ā±1.00ppm Frequency Stability Ā±0.50ppm to Ā±2.50ppm - Frequency calibration: Offset from nominal frequency measured at 25Ā°CĀ±2Ā°C - Frequency stability over temperature: referenced to the midpoint between minimum and maximum frequency value over the specified temperature range. Control voltage set to midpoint of control voltage (Note 1) - Frequency slope, minimum of 1 frequency reading every 2Ā°C, over the operating temperature range (Note 1): 0.1 to 1ppm/Ā°C ## **Outline (mm) = Pad 1 VC** - Static temperature hysteresis: frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25Ā°C: Ā±0.6ppm max - Supply voltage variation (Ā±5% change at 25Ā°C): Ā±0.1ppm max - Load variation (Ā±10% change, note 2): Ā±0.2ppm max - Long term stability, frequency drift over 1 year at 25Ā°C: Ā±1ppm max ## **Electrical Parameters** - Reflow shift: Two consecutive reflows as per profile after 1 hour recovery at 25Ā°C: Ā±1ppm max - Supply voltage range: 1.8 to 3.3V - Supply current (see note 2) - 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 the oscillator output section at 25Ā°C - Note 3: External AC-Coupled output requires an external capacitor ā‰„1nF recommended. - Note 4: Frequency shift ā‰¤1ppm after environmental conditions ## **Sales Office Contact Details:** UK: +44 (0)1460 270200 Germany: 0800 1808 443 France: 0800 901 383 USA: +1.760.318.2824 Email: info@iqdfrequencyproducts.com Web: www.iqdfrequencyproducts.com Printed on 21 Jul 16 15:23 using Model Data Sheet V1.2550 Page 1 of 4 **TCXO Specification** _**IQXT-260**_ ## **Frequency Adjustment** Pulling Ā±10ppm min Input Impedence 500kĪ© min **Operating Temperature Ranges** -40 to 85Ā°C ## **Output Details** Output Compatability Clipped Sine Drive Capability 10kĪ©//10pF Ā±10% Output: DC coupled (see note 3) ## **Output Control** Control voltage range: The nominal control voltage value is midway between the minimum and maximum.
