High levels of temperature stability are possible with the oven-controlled crystal oscillator.The OCXO is a very stable signal source because it uses an oven with a thermostat to keep its temperature above the surrounding temperature and thus constant.
Oven Controlled Crystal (Xtal) Oscillators is the term that gave rise to the acronyms for the OCXO. Utilizing quartz crystal resonators with a high tolerance, OCXOs typically adhere to the highest design standards.
They are significantly more expensive than other kinds of crystal oscillators due to the high tolerance crystals and additional oven hardware.OCXOs, like many other crystal-based products, come in a wide range of packaging options and styles.
Costs and performance levels must also be taken into account because they can vary greatly.Even though quartz crystals are relatively small compared to other LC resonant circuits, etc., their resonant frequency varies with frequency.
The Global Oven controlled(OCXO) oscillator market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Oven-controlled crystal oscillators (OCXO) are introduced by IQD. The IQOV-220 OCXO has low phase noise and high stability.
It has a short-term stability (Allan deviation) of 0.5ppt (tau=1s) with frequency stability performance down to 0.5ppb (parts per billion) across the entire industrial temperature range of -40 to 85°C.
According to IQD, the IQOV-220 is suitable for high-performance synthesizers, network clocks, radar, and satellite communications with a holdover spec of 6S over 24 hours, close in phase noise of typically -140dBC/Hz at 10Hz, and far out phase noise of typically -160dBc/Hz at 100kHz.
The IQOV-220 is available in 10 MHz and is packaged in a 36 x 27 mm hermetically sealed through-hole metal package, which is the industry standard.
The Sinewave OCXO has a frequency adjustment on Pin 2 that enables the frequency to be pulled by 0.4ppm (parts per million) with a control voltage of 0 to 8V, which will be sufficient to cover 10 years of ageing.
It can drive up to 50 loads and operates at 12V, consuming a maximum of 5W during warm up and 1.2W at steady state at 25oC.
