The importance of crystal oscillator in SSD, this article will let you understand in seconds!

Solid-state drives (SSDs) have become the mainstream device for modern computer storage. Compared with traditional mechanical hard drives, SSDs have higher read and write speeds, lower power consumption, and higher durability. Of course, the package size is also becoming smaller. As SSD capacity continues to grow and the performance requirements of application scenarios continue to improve, its crystal oscillator requirements are becoming more and more complex.

Several main parameters of temperature compensated crystal oscillator

In fact, there are many parameters for temperature-compensated crystal oscillators. In the actual application of temperature-compensated crystal oscillators, in addition to the main parameters such as nominal frequency, PPM accuracy and temperature stability, there are some other important parameters that need to be paid attention to. When the standard power supply voltage, standard load capacitance impedance, reference temperature and other conditions remain unchanged, the frequency accuracy of the temperature compensated crystal oscillator can reach more than 0.5PPM.

In recent years, with the continuous development of science and technology, high-speed electronic equipment has become increasingly popular. High-speed clock signals have become an important source of noise in electromagnetic compatibility radiation and conduction experiments. Effective suppression of them has become the focus of electromagnetic compatibility engineers. Although traditional countermeasures include circuit reconfiguration, matching, isolation, filtering and shielding, these methods often do not achieve the desired results, leaving engineers confused when dealing with problems caused by high-speed clock signals.

How to gradually determine the parameters and type when choosing a quartz crystal oscillator

Common equipment frequency parameters are between 10MHZ and 100MHZ. It is also necessary to determine whether a low-frequency crystal is used. When determining the crystal oscillator parameters, we must consider the specific application requirements and check the parameter markings on the crystal oscillator package to ensure that the purchased crystal oscillator parameters meet our requirements.
