IQXT-274 Datasheet | IQD

ISSUE 1; July 2016 Description The IQXT-274 with voltage control option, employs an analogue IC for the oscillator and temperature pensation. 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. Applications: Feature phone Wi-Fi Wi-MAX/W-LAN Frequency Parameters Frequency 10.0MHz to 40.0MHz Frequency Tolerance ±1.00ppm Frequency Stability ±0.50ppm to ±5.00ppm Frequency calibration: Offset from nominal frequency measured at 25°C Reflow shift: Two consecutive reflows as per profile after 1 hour recovery at 25°C: ±1ppm max 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 2°C, over the operating temperature range (Note 1): 0.05 to...
