21.2.2 Quartz Crystal Oscillator: History and Market The research of quartz crystal oscillator initiated by A.M. OCXO datasheets are available from the OCXO parametric search page. speaker, piezoelectric motors, valves), Generator (energy harvesting, cigarette lighter), Transducer (ultrasonic sonar devices), and Frequency standard (oscillator). In order to measure the force, a thin quartz plate is employed in a crystal-controlled electronic oscillator. We specialise in offering a customisation service to suit specific applications. The piezoelectric transducer consists of a piezoelectric crystal made up of piezoelectric material which develops electrical potential across its surface on application mechanical stress. IQD’s OCXO range includes frequencies up to 100MHz with a wide choice of package sizes, supply voltages and outputs available. Rakon has extensive experience in creating standard and customised Oven Controlled Crystal Oscillator (OCXO) solutions for the Telecommunications, Space and Defence markets. Our low phase noise OCXOs deliver exceptional phase noise performance down to -182dBc/Hz at 1MHz offset.Īs a previous division of Rakon, IQD maintains a close partnership as a worldwide channel partner supplying Rakon’s wide range of high stability OCXOs. This frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits. Traditionally this technology meant physically large devices with heavy power consumption however our latest models include some of the smallest OCXOs in the world. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a constant frequency. The frequency drift of the quartz crystal due to temperature shift is reduced by heating the crystal in an oven and so holding the temperature of the quartz at a fixed point. An OCXO offers frequency stabilities even tighter than those offered by a TCXO. What are crystals used for in electronics A crystal is a piezoelectric device that uses mechanical resonance to achieve a very precise frequency output. Oven Controlled Crystal Oscillators (OCXOs) deliver the ultimate piezo electric performance with stabilities down to less than ☑ppb. The crystal oscillator uses the inverse piezoelectric effect principle.
