ECS晶体振荡器设计应用笔记

什么是振荡器？

振荡器是一种产生重复信号的电子电路。根据应用，该信号可以是多种形式。一些应用程序需要一个基本时钟来维持进程的操作间隔。其他应用要求时钟具有非常清晰的波形和严格的稳定性，以产生高质量的通信和数据传输。

在模拟应用中，例如使用超外差收发信号链的RF无线电收发器，通常会发现正弦输出波形。正弦波是一种连续波，代表平滑的周期性振荡。在RF通信中，石英晶体振荡器正弦波输出为收发器提供精确的低噪声频率参考。

在数字电子学中，我们看到方波输出。方波是一种以稳定频率从最小振幅到最大振幅交替变化的波形。理想方波的最小和最大周期相等，占空比为50/50%。实际上，占空比会有一些变化，因此45/55%或60/40%可能更典型。方波输出信号有许多用途，但广泛用于电路或微处理器中指令执行的定时。

About IoT and M2M

Essentially, IoT and M2M describethe network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. Driven by several factors including the growth in the availability of Broadband Internet, which reduces the cost of connecting, and the related increase in Wi-Fi capabilities as well as sensors built into myriad technologies, this has been described as the “perfect storm” for the IoT. Almost any device with an on and off switch that can be connected to the Internet (and/or to each other) – anything from cell phones, coffee makers, washing machines, headphones, lamps, wearable devices, cars, as well as machine components in the engine of a jet airplane or the drill of an oil rig. According to analyst firm Gartner, by 2020 there will be over 26 billion connected devices. Others think this figure could be too conservative by a factor of four.

In a current vertically integrated era, where applications such as complex data and video along with voice, are increasing in demand, advanced technologies of high-speed information transfer require continuous improvements of information sharing systems. The World Wide Web has become an essential tool in our daily life when it comes to accessing various types of information/business databases, video conferencing or manufacturing networks. Enabling efficient communication flow over existing infrastructure has become challenging in order to satisfy demanding user requirements. High-speed data/video and voice channels along with effective routing systems have been created as a result. 

在当前的垂直集成时代，随着需求的增加，高速信息传输的先进技术要求改进信息共享系统。网络已成为我们日常生活中访问各种类型的信息/商业数据库、视频会议或制造网络。通过现有基础设施实现高效的通信流为了满足苛刻的用户要求，变得具有挑战性。高速数据/视频和语音因此，已经创建了具有有效路由系统的信道。
Data Networks 

数据网络

For the purpose of this discussion, we can associate the flow of information within network channels to water flow within very complex system of pipelines of different shapes and sizes. Long haul channels that transfer information from state-to-state or city-to-city are called “TRUNKS”. Trunks connect multiple central office locations while utilizing fiber optics and high bandwidth cabling meshes along with highspeed routers and core switching systems. This accommodates the transfer of heavy masses of data packets (also called high band width data transporters). Once data packets reach a given central office destination (close-by to the final destination of the end user), they are transferred through soft-switching equipment to narrower data transport channels ultimately leading to the end-users (subscribers).  

为了进行讨论，我们可以将网络渠道内的信息流与水在不同形状和尺寸的非常复杂的管道系统中流动。长途通道从一个州到另一个州或从一个城市到另一座城市的信息传递被称为“TRUNKS”。中继线连接多个中心办公室位置，同时利用光纤和高带宽布线网络以及高速路由器和核心交换系统。这可以容纳大量数据的传输数据包（也称为高带宽数据传送器）。一旦数据包到达给定的中心局目的地（靠近最终用户的最终目的地），它们通过软交换进行传输设备到更窄的数据传输信道，最终导致最终用户（订户）。

In many cases the subscribers are located within enterprises (i.e. business organizations, hospitals, office buildings, etc.) that share internal communication lines and network channels to support several business activities. In such cases, an internal high-speed network is typically installed. 

在许多情况下，订阅者位于企业内部（即商业组织、医院、办公室建筑物等）共享内部通信线路和网络通道以支持多个业务活动。在这种情况下，通常会安装内部高速网络。

Ethernet Standard 

以太网标准

Ethernet has evolved into the most widely implemented networking protocol today. Fast Ethernet increased the data speed from 10 Megabits per second (Mbits/s) to 100 Mbit/s to and from the users terminal. Gigabit Ethernet was the next iteration, increasing the speed to 1,000 Mbit/s. The initial standard for Gigabit Ethernet was issued by the IEEE in June 1998 as IEEE 802.3z. 

以太网已发展成为当今实现最广泛的网络协议。而以太网需要进口晶体振荡器支持，快速以太网将往返用户的数据速度从每秒10兆比特提高到每秒100兆比特航空站千兆以太网是下一代，将速度提高到1000 Mbit/s。初始标准IEEE于1998年6月发布了用于千兆以太网的IEEE 802.3z。

Gigabit Ethernet access equipment is available in different speeds and bandwidth. Most common systems operate with 3.125Gbits/sec and 10Gbits/sec. 10 Gigabit Ethernet over twisted pair has just been completed, but as of June 2006, the only currently available adapters for copper wire requires special cabling and is limited to 15 meters for point-to-point communications. Major Gigabit Ethernet manufacturers include Cisco Systems, Broadcom (chipset manufacturer), Netgear, D-Link, Intel, Adtran and others.  
千兆以太网接入设备有不同的速度和带宽。最常见系统以3.125Gbits/sec和10Gbits/sec运行。双绞线上的万兆以太网已完成，但截至2006年6月，目前唯一可用的铜线适配器需要特殊布线，点对点通信限制在15米以内。主要千兆以太网制造商包括Cisco Systems、Broadcom（芯片组制造商）、Netgear、D-Link、Intel、Adtran以及其他。CTS时钟振荡器支持以太网应用.
