Taking Stock of the Practical Application Advantages of Crystal Oscillators
Many devices today are inseparable from the use of oscillators, and the application of crystal oscillators is more common. When purchasing an oscillator, you must naturally choose a specific type according to application requirements, and at the same time, you must pay attention to the parameters of the specific crystal oscillator. YXC will take stock of the common application advantages of crystal oscillators.
Crystal oscillator output frequency accuracy is higher
Nowadays, crystal oscillators are used in common intelligent communication systems. This is because the crystal oscillator itself has the advantage of high output frequency accuracy. Generally, crystal oscillators are used in radio frequency communication equipment or remote control equipment because of their high-frequency accuracy. Moreover, the temperature drift and time drift of crystal oscillators are relatively small, and the frequency of crystal oscillators is unadjustable and single. These characteristics make crystal oscillators more suitable. Used in intelligent communication equipment.
Crystal oscillator has low loss and longer life
For any electronic product, one of the requirements for the components used is low loss and stability, and crystal oscillators have the characteristics of low loss and long life. Because the Q value of the quartz crystal itself is very high, using a quartz crystal as an oscillator has very small losses and can also ensure stable oscillation. Crystal oscillators are currently used in many filters. One of the reasons is that their losses are small and stable, and they can obtain very stable and steep bandpass or bandstop curves. These are the advantages of crystal oscillators in applications.
Crystal oscillator is more stable and reliable
The advantage of the crystal oscillator is not only that it is stable enough and has low consumption, but also has strong scalability to meet the use requirements of equipment in more fields. Taking the continuously developing TV technology as an example, many color TVs now use 500KHZ or 503KHZ crystal oscillators because their reliability and stability are constantly improving. Like the 500KHZ crystal oscillator mentioned just now, the oscillation source of the line and field circuits passes through 1 When divided by /3, the line frequency is 156.25Hz, so its stability is greatly improved. It is not only the application in color TV that reflects the scalability of crystal oscillators. The application of crystal oscillators can be seen in communication system equipment. All high-performance quartz crystal oscillators will be widely used in communication networks or wireless data transmission and in terms of high-speed digital data transmission, these can reflect the high scalability and stability of the crystal oscillator.
As equipment in more fields begins to have higher requirements for the stability and frequency accuracy of oscillators, crystal oscillators will be used more widely, and the advantages of crystal oscillators are not only those just mentioned but also often in specific The crystal oscillators used in the equipment also has specific practical advantages, so users can choose a more suitable crystal oscillator type and parameters according to their needs.
