Quartz crystal oscillator is the most core electronic component in 5G technology, which is used to provide reference clock signal and receive transmission signal. Because 5G has very high requirements on the use of network equipment, the network equipment has to process a large amount of data workload, and the device circuit needs to use crystal vibration and other components to cooperate with the command to get the pulse signal source to work, which means 5G has high requirements on the stability and reliability of crystal vibration. In order to meet the requirements of 5G, intelligent products must be equipped with high-end and fast 5G products, which must be matched with high-precision microchip crystal oscillator. Based on the current market demand, crystal oscillator will develop towards high-frequency and miniaturization.
