For the crystal oscillator, one of its most significant characteristics is the stability of the operating temperature, this performance can also determine the price of the oscillator. Higher stability or a wider temperature range means that the price of the device is higher.



The industrial standard determines the range of -40 ~ +75 ° C, which is to meet the needs of designers, if -30 ~ +70 ° C standard, there is no need to require a wider temperature range. When designing, the stability of the oscillator should be specified in combination with the actual needs of the specific application. A high indicator means a higher price.



Crystal aging can also have a big impact, crystal aging can make the output frequency change according to the logarithmic curve, according to the rule, in the first year of product use is often more common phenomenon.

There are many other factors that determine the stability of the crystal oscillator, including power supply voltage, load change, phase noise and jitter, and these indicators need to be specified one by one. For industrial products, sometimes also need to put forward vibration, shock indicators, military supplies and aerospace equipment often have more requirements, such as pressure change tolerance, tolerance when exposed to radiation and so on.



What is the quality of the crystal oscillator, which is a lot of buyers are more concerned about, the introduction of the above content, but also hope to help you better understand the stability of the crystal oscillator and what elements are related.
