Euroquartz launches new tight stability clock oscillators from Statek

Frequency control specialist, Euroquartz has launched a new range of clock oscillators from Statek offering tight frequency stability of ±20ppm over the military temperature range and ±10ppm for industrial applications. Available in frequencies from 10 to 55MHz, the new STXO range also offers low RMS jitter and low phase noise.


State-of-the-art design, process, manufacturing and test capabilities have made the development of this ultra-miniature 3.2 x 2.5mm STXO oscillator possible. Key performance capabilities include low RMS jitter typically less than 300fs, typical noise floor less than -161dBc/Hz, high shock survival options (>20,000g) and ultra-low Allan Deviation and period jitter (1.4ps RMS).


Supply voltage options are 2.5 and 3.3V ±10 per cent with low current consumption of 3.0mA (no load across temperature range). Offering 15pF CMOS output load with enable/disable and tri-state functions, the new Statek STXO range delivers fundamental frequency output with no PLL artefacts and is housed in a hermetically-sealed ceramic four-pad surface mount package.


Offered in versions for industrial applications over -10 to +85°C and military applications over -55 to +125°C, the new STXO clock oscillators are available with full military testing per MIL PRF 55310 on request. Tighter frequency stability performance can also be provided to special order.


Additional specifications include start-up time of 5ms maximum, rise/fall time of 5ns maximum, duty cycle of 45 per cent minimum/55 per cent maximum and low ageing of 2ppm in first year. Defence and aerospace applications include smart munitions, communications, guidance and navigation.


Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the electronics manufacturing industry worldwide. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs covering a broad spectrum of applications including military and aerospace, communications, general electronics, computing, control systems and petrochemical among many others.
