OCXO (Oven Controlled Crystal Oscillator) is kind of high precise frequency standard, it can generate a stable oscillation signal which is used to be time clock of various electronic devices, such as drive computer, network system, telecommunication equipment. Precision performance of time clock is directly connected with the whole system’s performance and stability. Thus, OCXO is one of essential components of electronic system.With wide establishment of 5G, the demanding for OCXO is rising quickly, one small 5G base station at least requires one OCXO, and micro site may demand for over 10 OCXO.

The working principle of OCXO employs piezoelectric effect, enables crystal oscillation frequency to be stabilized, and controls its temperature through constant controlled circuit, in order to guarantee stability of its oscillation frequency.Piezoelectric effect means when crystal unit is suffered from mechanical stress, it causes uneven charge distribution inside the crystal, then produces electric potential difference and leads to crystal oscillation.

As OCXO takes special protection circuit and protection measures,it has ultra low stability (<-175dBc), low aging ( annual 0.05-0.5ppm). With strength of high precision, excellent stability and long life, it is widely used in the field of high precise timing, precise control.

The key parameters of OCXO include rated frequency, accuracy, frequency stability, aging, consumption and operating temperature etc. 

As accuracy and stability of OCXO play an important role on performance of electronic equipment, normally the manufacturer will try to improve its accuracy and stability during OCXO production. Since every cycle is possible to affect quality and performance of OCXO, thus, strict quality control process is of great importance. Chengdu Spaceon has obtained certificate of ISO 9001/2015 Quality Management System,based on over 20 years experience of OCXO design and production, we are striving to provide our customers with high precision, high accuracy OCXO products.
