OCXO offers short term stability, low phase noise

The latest oven controlled crystal oscillator (OCXO) from IQD, the IQOV-220, offers frequency stability performance down to ±0.5 parts per billion over the full industrial temperature range of -40 to +85 degrees C with a short term stability (Allan Deviation) of 0.5 ppt (tau=1s). Holdover spec is six micro seconds over 24 hours, a close in phase noise of typically -140dBC/Hz at 10Hz and far out phase noise of typically -160dBc/Hz at 100kHz, making the IQOV-220 suitable for high performance synthesisers, network clocks, radar and satellite communications, says IQD.

The IQOV-220 is available in 10MHz and in a 36 x 27mm industry standard hermetically sealed through-hole metal package.

The sinewave OCXO is capable of driving up to 50 Ohm loads and operates at 12V, consuming a maximum of 5.0W during warm up and 1.2W maximum at steady state at 25 degrees C.

The OCXO has a frequency adjustment on pin 2 which enables the frequency to be pulled by ±0.4 parts per million with a control voltage of 0 to 8V which will be sufficient to cover 10 years ageing, assures IQD.

The OCXO joins others from IQD, including low phase noise performance and small packages.

An export license will be required by customers outside of the United Kingdom.

IQD has over 40 years’ experience in the manufacture of frequency products. It is part of the Würth Elektronik eiSos group.
