Euroquartz Eqxo-75uie Extended Industrial Temperature Ruggedized High-reliability Oscillator

The EQXO-75UIE series is a ruggedized high-reliability, high temperature range clock oscillator in a standard format 7x5mm SMD ceramic package designed for demanding and vibrating industrial applications

Euroquartz Eqxo-75uie Extended Industrial Temperature Ruggedized High-reliability Oscillator

Saelig Company, Inc. has launched the Euroquartz EQXO-75UIE Extended Industrial Temperature Ruggedized High-Reliability Oscillators.  The EQXO-75UIE series is a ruggedized high-reliability SMD clock oscillator. Designed for demanding industrial applications, it provides reliable operation with excellent frequency stability across an extended industrial operating temp range of -40degC to +105degC. Mechanical shock survivability has been tested to 1500G MIL-STD-883K Meth 2002.5, Condition B.

Temperature stabilities of ±50, 75 & 100ppm are available, with tighter options by request (dependent on conditions). This component, available with short lead time, has no ITAR restrictions. All EQXO-75UIE crystals are pre-aged as part of an additional manufacturing process in order to improve long-term application stability.  With an aging specification of ±1ppm maximum for the first year, an even tighter aging specification is available by request.

EQXO-75UIE Series Features

  • Frequency Range: 2.00MHz to 60.00MHz
  • Operating Temperature: -40degC to 105degC
  • Shock Survivability: 1500G
  • Supply Voltages: 2.5V, 3.3V and 5V
  • Crystal Stabilization: 96 hours at 100degC
  • ITAR Restriction:  none

If phase noise is a critical project design consideration then it is important to realize that vibration causes a degradation in both spectral output and phase noise.  Even moderate levels of vibration can significantly introduce an unwanted signal variation. The acceleration-sensitivity (“g-sensitivity”) of components is often a limiting factor in these applications, and quartz crystals often prove to be a critical limiting component in a design.


The EQXO-75UIE Series of ruggedized, high-reliability, high temperature clock oscillators are made by European frequency product specialist Euroquartz, an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the worldwide electronics industry. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers for military and aerospace, communications, general electronics, computing, control systems and petrochemical applications.  The EQXO-75UIE Series is available now from Euroquartz’ USA technical distributor Saelig Company, Inc.
