Euroquartz has launched a new surface mount oscillator from Statek, which is designed for applications requiring shock survivability to 10 000 G and higher.
The new CXOMHG oscillators are high-shock versions of the CXOM range and comprise a miniature quartz crystal and a CMOS/TTL compatible hybrid circuit in a low profile ceramic package with a small footprint. Clock frequencies from 300 kHz to 120 MHz can be supplied in hermetically sealed packages measuring 6,5 x 5 x 1,4 mm.
Designed for surface mount applications using infrared, vapour phase or epoxy mount techniques, the new oscillators feature low power consumption, optional output enable/disable with tri-state and low EMI emission.
Specifications include 5 V supply voltage, calibration tolerance of ±100 ppm, frequency stability of ±50 ppm for commercial (±100 ppm for industrial and military), supply current from 4 to 14 mA (10 to 50 MHz), output load of 15 pF and ageing (first year) of 10 ppm maximum. Operating temperature ranges from -10 to +70°C, -40 to +85°C and -55 to +125°C are available for commercial, industrial and military applications respectively.
Typical applications in military/aerospace include smart munitions and projectile electronics, while industrial applications include engine control and down-hole drilling.
