When we purchase crystal oscillators, we often have to pay attention to the type, in which the crystal oscillator can be divided into single-ended or differential crystal oscillators according to the division of labor according to the output mode. Considering that many customers will ignore parameters such as output mode when purchasing crystal oscillators for the first time, let's talk about the difference between differential crystal oscillators and ordinary crystal oscillators, and what are the advantages in practical applications?
Differential crystal oscillators and single-ended crystal oscillators have different anti-interference capabilities
When we need to purchase and use crystal oscillator products, we naturally cannot ignore the type of output. The ordinary crystal oscillators that we usually see are single-ended crystal oscillators with a single output mode, and the output modes of the relative differential crystal oscillators are more diverse. The advantage of single-ended crystal oscillator is that only one line can output the signal, but the disadvantage is also obvious that the anti-interference ability is poor, so the high-speed signal above 100MHz will not use the single-ended crystal oscillator, and the signal of the relative differential crystal oscillator is more stable and reliable, because it has a strong anti-interference ability.
Differential crystal oscillator signal recognition and processing capabilities are stronger
In fact, compared with single-ended crystal oscillators, differential crystal oscillators not only have strong anti-interference ability, but also have many practical advantages in signal processing. In practical applications, the differential crystal oscillator can easily distinguish small signals, which can not be done by single-ended crystal oscillators, and the differential crystal oscillator is highly immune to external electromagnetic disturbances, and at the same time, it can also accurately and quickly solve the bipolar signal, which is not guaranteed by other types of crystal oscillators, so in high-speed signal processing or single power supply systems, differential crystal oscillators are used, and have always had a good reputation for use.
The differential crystal oscillator package type is more convenient for users to choose
When purchasing a differential crystal oscillator, it can also be selected in a variety of packages, which makes it more versatile. Considering the specific use requirements, the size is divided into 7050 and 5032 and smaller 3225, etc., different package volumes can be better adapted to specific applications, and at the same time, the purchase order can also be adjusted according to the budget, procurement planning and application requirements at the time of purchase, so as to ensure the purchase of differential crystal oscillator products that are satisfactory to all aspects.
With the increasing demand for high-speed signal processing in more and more devices, and the emphasis on signal anti-interference ability, the use of better differential crystal oscillators in practical applications has become more frequent. Before purchasing this kind of crystal oscillator products, users should understand the differences between different types of crystal oscillator parameters and outputs, and understand the precautions for actual welding and installation, so as to ensure the purchase of satisfactory differential crystal oscillator products and get perfect after-sales service.
At present, differential crystal oscillators have been applied to satellites, rockets and other fields. It can be used in communications, navigation, automobiles, aerospace, defense, industry, telecommunications, consumer markets, fixed communications, consumer electronics, automotive electronics, Internet of Things, mobile phones, walkie-talkies, GPS Beidou locators, automotive electronic systems, reversing radars, small base stations, LTE, RFID, laser rangefinders, notebooks, tablet computers, digital group communication systems, instrumentation and many other fields.
