        Many mobile phones use crystal oscillator series. If it is used on the mobile phone motherboard, the current mainstream is the small-size patch of TCXO, which is basically controlled by foreign manufacturers, with Japan winning. However, there is a trend that some of them can be replaced by patch resonators, such as 5032. There are basically threeorfour domestic companies that can do it in the field of patch resonators. The manufacturers are mainly distributed in Taiwan, Japan and the United States. If it is other parts of the mobile phone, such as display module, camera module, etc., the application part of the crystal oscillator is generally a more common 49smd or a small-size ceramic patch. 49smd needless to say, the domestic limit of small-size ceramic patches is basically 2.0*1.6 or more. At present, the mainstream is still Japan and South Korea.

   with the diversification of vehicle equipment, the demand for RTC modules applied to on-board products also surged. In this market demand, the dsx530gk quartz oscillator developed by Japan''s great vacuum can be produced in real time in the special automobile production line, which can ensure its high reliability. For vehicle accessories that need high reliability, this quartz oscillator is the most suitable product, which has higher reliability and can provide higher cost-effectiveness. The direct oscillation mode is adopted for operation, so that it has three different frequency range applications, including 8 ~ 12Mhz, 12 ~ 20MHz and 20 ~ 40MHz, which meets the high-speed and diverse frequency interface requirements of the next generation of automotive electronic products, and drives the high-speed clock requirements of low-voltage operation. It also adopts the unique technology of large vacuum itself to try to improve the vibration impedance and solve the poor oscillation and other factors, which can be applied in the application fields of vehicle navigation equipment, tire pressure detection device, ABS brake system, etc.

   the frequency range of nx3225da series crystals of the company is 16 ~ 55mhz, and the standard frequencies are 16, 20, 24, 26 and 32mhz, which makes its application frequency range very wide. It can also be applied to a variety of products, including all frequencies between 16mhz and 55mhz, which can be achieved by direct oscillation mode. This also shows that the reference frequency inside the nx3225da quartz crystal module is the same as the external output frequency. This design makes the signal jitter of this component very low, and can provide a stable and reliable clock for sensitive product applications, such as telecommunications products and high-speed data transmission. The wide operating temperature range, about -40 ~ +150 ℃, makes this component also applicable to automotive applications. The frequency stability of ± 50x10-6 proves that even in the field of high-tech level, it can also have standardized solutions, which are compatible with the requirements of CMOS and TTL, and highlights the versatility of nx3225da.

   CSTCC_ G_ The design method of a oscillator fully conforms to the design concept of energy saving required by Murata manufacturing in the past; Therefore, the power consumption of the whole component is very low, even in standby mode, its current consumption is very low. In addition, the oscillator is fully compatible with the programmed PLL type quartz oscillator in terms of external dimensions. By using this feature, the design threshold can be reduced when designing products. In the design and development stage of the product, it can also provide multiple groups of components with different output frequencies to be integrated into the standard package size, which saves 75% of the circuit board area and 40% of the cost compared with the traditional solution.
   to significantly improve the reliability and efficiency of the oscillator according to the three important indicators of initial accuracy, temperature stability and aging impact, the key is to adopt the oscillator architecture based on dspll. If designers want to implement a saw based voltage controlled oscillator (VCXO), they must use products with a wide range of tunningslope to make up for the poor initial frequency accuracy, temperature stability and aging characteristics of saw. Therefore, cstcc with the above characteristics_ G_ A. It will become the most reliable choice in the fields of telecommunications, networks, industry, automotive applications, and other product applications.
