最佳耦合保证晶体既不过度驱动也不欠驱动。超速的晶体，特别是在当今的低功率品种会导致应力断裂和整体可靠性在操作期间的担忧。驱动不足可能导致启动失败或振荡最终衰减。此外，还有频率精度方面的问题。带有皮尔斯振荡器的mcu提供可配置的跨导，也可以优化最低的功耗。如果没有仔细的分析和验证，通过试错进行的设计可能会导致上述任何问题。

SG-8101CGA Epson has a X1G005171003900 smart TV and smart speaker appliances

In recent years, smart home has been a hot topic in the home appliance industry. With the development of the Internet of Things and the accelerated popularization of 5G network, the popularity of smart home is also gradually rising. Although smart TV, smart speakers and other smart categories of smart home appliances have been accepted by consumers, the market still lacks successful cases due to replacement costs, uneven degree of intelligence between categories, and low degree of standardization between brands. For example, for all kinds of disinfectants, forehead temperature guns, blood oxygen meters and other products, which are in global shortage, We have actively participated in its application and optimization, and launched a CMS8S6990 blood oxygen meter solution with low power consumption and high cost performance High-precision 24bit-ADC and large screen LCD display CMS8H5101L forehead temperature gun solutions, as well as cost-effective SC8F3715 / SC8F5776 series disinfection set solutions, help customers to achieve a balance between performance and cost competition, in the actual promotion process of the process of good market recognition. According to Xia Yu forecast, this kind of market space may be bigger than imagined.
