IoT Solutions & Product Frequency Reference Guide

The Internet of Things [IoT] is the new wireless touchstone connecting live information, control mediums and hubs to wireless devices such as phones, tablets and computers. These applications are widely used in Smart Homes, Smart Cities, Smart Factories, Smart Healthcare, Smart Agriculture and Smart Energy. Communication protocols and transmission frequencies are guided by standards such as IPv6, UDP, QUIC, Aeron and uIP. As a result, next generation MCUs, SoCs or FPGAs created to meet new communication requirements have challenged chipset designers to develop architectures that provide improved fast communication along with low noise performance, but also at low power consumption. Utilizing low power elements helps continuous operation over long periods of time, but also increase challenges like reductions in oscillator gain margin and signal to noise ratios.

CTS Crystal Currently there are billions of connected IoT devices. An exponential increase of connected devices is expected over the next decade, as 5G infrastructures will be readily available along with more affordable consumer devices. The seemingly limitless connections promised by 5G will continue to burden infrastructures and push the boundaries of chipset performance, requiring the timing block and associated frequency reference to provide very reliable low power operation.

物联网解决方案和产品频率参考指南

物联网[物联网]是将实时信息、控制媒体和集线器连接到手机、平板电脑和电脑等无线设备的新的无线试金石。这些应用程序被广泛应用于智能家居、智能城市、智能工厂、智能医疗保健、智能农业和智能能源等领域。通信协议和传输频率以IPv6、UDP、QUIC、Aeron和uIP等标准为指导。因此，为满足新的通信需求而创建的下一代mcu、soc或fpga已经向芯片组设计者提出了挑战，要求他们能够开发出能够提供改进的快速通信、低噪声性能和低功耗的架构。利用低功率元件有助于长时间连续运行，但也会增加降低振荡器增益边际和信噪比等挑战。

目前，已有数十亿个已联网的物联网设备。随着5G基础设施将与更实惠的消费设备一起随时可用，预计联网设备在未来十年将呈指数级增长。5G所承诺的看似无限的连接将继续加重基础设施的负担，并推动芯片组性能的边界，需要定时块和相关的频率参考来提供非常可靠的低功率操作。
