To solve this problem, it is necessary to check whether the crystal oscillator is physically damaged, such as whether it is broken, bent or oxidized. If this is the case, a new crystal oscillator needs to be replaced.
In addition, if the crystal oscillator has no obvious physical damage, but still can't provide frequency information, it may be caused by other circuit faults or connection problems. At this time, you can consider checking whether the circuit components around the crystal oscillator, such as capacitors and resistors, are working normally. You can also check whether the crystal oscillator connection is good, loose or poor contact.
In terms of development, crystal oscillator is a very important part of modern electronic equipment, which is not only widely used in computer, communication equipment and other fields, but also plays an important role in various control systems and sensors. Therefore, understanding the principle, working mode and common troubleshooting methods of crystal oscillator is very helpful for maintaining and repairing electronic equipment. At the same time, regular inspection and maintenance of the state of key components such as crystal oscillator can improve the stability and reliability of the equipment and prolong its service life.
