Euroquartz takes up Greenray’s ultra-low phase noise VCXO
Frequency control specialist, Euroquartz has launched an ultra-low phase noise voltage-controlled crystal oscillator (VCXO) from US manufacturer Greenray Industries. The new surface mount devices also offer low g-sensitivity performance making them suitable for use where vibration conditions are encountered.
Greenray’s N623-1 VCXO offers nominal 100Mhz frequency sinewave output from a 9 x 14mm SMD package with typical phase noise performance ranging from -85dBc/Hz at 10Hz frequency offset up to -175dBc/Hz at 1MHz frequency offset. Phase noise is a critical characteristic in many applications including communications and digital systems as well as high performance radar installations. The new N623-1’s low-g sensitivity performance ensures that phase noise performance is maintained under vibration conditions enabling their use as stable reference sources in communications, aerospace and defence systems and applications.
Additional specifications include supply voltage of 5.0V DC, current requirement of 30mA, typical load of 50-Ohm, power level at 25 degrees C of 12dBm typical and operating temperature range from -40 to +85 degrees C. Frequency variation over the full operational temperature range is ±15ppm while frequency versus supply voltage is ±1ppm for ±0.25V change. Ageing characteristic over one year is less than 1ppm.
Other frequencies and options are available to special order. Environmental specifications include random vibration to MIL-STD-202, Meth 204, Cond A and mechanical shock per MIL-STD-202, Meth 213, Cond C.
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 range of customers including major OEMs covering a spectrum of applications, including among others defence and aerospace, communications, general electronics, computing, control systems and petrochemical.
