- [技术支持]时钟晶体振荡器的使用与终端设计2019年09月05日 16:50
tyle="font-family:calibri"> 在当今的高性能系统中,需要一个出色的时钟源。随着专用集成电路(ASIC)的速度和性能达到更高的限制,分配该时钟源以驱动多个设备的需求变得更加困难。由于相关的快速边沿速率,系统中部署的较高频率导致长PCB迹线表现得像传输线。保持平衡系统需要适当的端接技术来实现应用中的跟踪路由。本应用笔记将重点介绍推荐的终止技术;关于输出负载的评论,并提供一些设计师要考虑的布局指南。
tyle="font-family:calibri">传输线理论简介
tyle="font-family:calibri">通常,大多数时钟源具有低阻抗输出。当这些器件用于驱动具有大阻抗的负载时,存在阻抗不匹配。根据应用条件,此阻抗不匹配会导致负载产生电压反射,从而产生时钟波形中的步进,振铃以及过冲和下冲。这可能通过降低负载处的时钟信号,错误的数据时钟和产生更高的系统噪声而导致系统性能不佳。
tyle="font-family:calibri">为了减少电压反射,需要正确终止信号迹线。适当终止的设计考虑因素可以用两个语句来概括:
tyle="font-family:calibri">1.使负载阻抗与线路阻抗相匹配
tyle="font-family:calibri">2.使源阻抗与线路阻抗匹配
tyle="font-family:calibri">对于大多数设计,第一种说法是首选方法,因为它消除了返回时钟源的反射。这样可以减少噪音,电磁干扰(EMI)和射频干扰(RFI)。
tyle="font-family:calibri">下图显示了阻抗不匹配对时钟源的影响
th="698" height="253" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps1.jpg">tyle="font-family:calibri">
tyle="font-family:calibri">常用终止技术
tyle="font-family:calibri">如上所述,为了减少电压反射,必须正确地终止迹线。 传输线的四种基本端接技术是串联,并联,戴维宁和AC。
tyle="font-family:calibri">系列终止
tyle="font-family:calibri">串联终端消除了时钟源的反射,有助于保持信号质量。 这最适合驱动少量负载的TTL器件,因为时钟输出阻抗小于传输线特性阻抗。 图1显示了一系列终端。 电阻尽可能靠近时钟源放置。 R的典型设计值为10Ω至75Ω。
th="388" height="218" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps2.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">R的值可以大于阻抗差,以便产生稍微过阻尼的状态并且仍然消除来自时钟源的反射。
tyle="font-family:宋体">系列终端的主要优点是:
tyle="font-family:宋体">1.简单,只需要一个电阻器
tyle="font-family:宋体">2.功耗低
tyle="font-family:宋体">3.在驱动高容性负载时提供电流限制;这还可以通过减少接地反弹来改善抖动性能
tyle="font-family:宋体">系列终止的主要缺点是:
tyle="font-family:宋体">1.增加负载信号的上升和下降时间;这在一些高速应用中可能是不可接受的
tyle="font-family:宋体">2.无法驱动多个负载
tyle="font-family:宋体">平行和戴维宁终结
tyle="font-family:宋体">接下来的三种终端技术可提供更清晰的时钟信号,并消除负载端的反射。这些终端应尽可能靠近负载放置。
tyle="font-family:宋体">图2描绘了并行终端。并联终端消耗的功率最大,不建议用于低功率应用。它也可能改变占空比,因为下降沿将比上升沿更快。它比串联终端具有一个优点,即上升和下降时间的延迟大约是一半。
th="269" height="161" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps3.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">如图3所示,戴维宁终端将比并联终端消耗更少的功率,并且通常用于PECL应用,50Ω线路匹配至关重要。 R的总值等于传输线的特征阻抗。 如果需要过阻尼状态,则R的总值可略小于特征阻抗。 戴维宁终端的主要缺点是每条线路需要两个电阻器,并且在终端附近需要两个电源电压。 建议不要将此端接用于TTL或CMOS电路。
th="258" height="190" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps4.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">AC终止
tyle="font-family:宋体">AC端接,如图4所示,在并联支路中增加了一个串联电容。 由于RC时间常数,电容会增加时钟源的负载和延迟,但在稳态条件下将消耗很少或没有功率。 通常不建议使用此终端,因为它会通过增加传播延迟时间来降低时钟信号的性能。 为了保持有效终止,C L的值不应小于50pF。 较大的C L值将允许时钟边沿的快速转换,但随着电容器值的增加,较高的电流电平将通过,从而导致功耗的增加。 选择大于走线阻抗的R L值,以考虑负载输入阻抗的泄漏。
th="255" height="179" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps5.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">输出负载简介
tyle="font-family:宋体">应注意不要使时钟源过载。 如果使用单个时钟源来驱动多个负载,则如果总负载超过时钟源的驱动能力,则会发生波形劣化。
tyle="font-family:宋体">过载的一些常见症状是波形削波,对称不平衡,信号幅度减小以及上升和下降时间值的变化。 通常随着时钟频率的增加,源驱动更高负载的能力将降低。 请务必参考时钟源规范以获得最大负载能力。
tyle="font-family:宋体">下图显示了重载对时钟源的影响。
th="662" height="263" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps6.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">通用时钟输出类型
tyle="font-family:宋体">CTS时钟振荡器设计已经开发出来,具有各种封装选项,输入电压和输出类型。
tyle="font-family:宋体">HCMOS和HCMOS / TTL兼容
tyle="font-family:宋体">今天的CTS设计提供“双兼容”振荡器,它们是能够驱动TTL应用的HCMOS输出类型。 由于转换时间较短,这些设备固有地具有更大的过冲和欠冲。 这可能不适合具有严格EMI要求的旧TTL设计。
tyle="font-family:宋体">CTS生产两种流行的HCMOS / TTL兼容时钟振荡器CB3 / CB3LV和型号636。

tyle="font-family:宋体">LVPECL和LVDS
tyle="font-family:宋体">与HCMOS逻辑技术相比,CTS LVPECL和LVDS逻辑输出设计具有许多优势。
tyle="font-family:宋体">LVPECL和LVDS技术从正电源获得其工作功率,从而实现与负载点处的HCMOS逻辑接口的必要兼容性。 这些逻辑输出还具有:
tyle="font-family:宋体">1.降低系统抖动; 由于较小的特征过渡区域
tyle="font-family:宋体">2.上升和下降时间更快

th="476" height="329" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps8.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">布局指南
tyle="font-family:宋体">在印刷电路板布局过程中采用良好的设计实践将最小化先前讨论的信号劣化。 PCB设计的一些常见指南是:
tyle="font-family:宋体">1.将时钟源物理定位在尽可能靠近负载的位置
tyle="font-family:宋体">2.限制时钟信号的走线长度
tyle="font-family:宋体">3.不要将时钟信号靠近电路板边缘
tyle="font-family:宋体">4.尽量避免在时钟信号路由中使用过孔。 过孔会改变走线阻抗,从而引起反射。
tyle="font-family:宋体">5.不要在电源和接地层上布设信号走线
tyle="font-family:宋体">6.避免在轨迹中出现直角弯曲,如果可能,请保持直线行程。 如果需要弯曲,请使用两个45°角或使用圆形弯曲(最佳).
th="454" height="135" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps9.jpg">tyle="font-family:宋体">
tyle="font-family:宋体">7. V CC与时钟源地之间的去耦电容对于降低可能传输到时钟信号的噪声至关重要。 这些电容必须尽可能靠近V CC引脚。
tyle="font-family:宋体">8.为避免串扰,请在多个时钟源和高速开关总线之间保持适当的间隔。
tyle="font-family:宋体">9.差分跟踪路由应尽可能接近,以获得高耦合系数。 路由的长度应相等,以避免阻抗不匹配,从而导致不同的传播延迟时间。
tyle="font-family:宋体">10.使用单个时钟源驱动多个负载时,请考虑拆分路由。 使各个布线长度尽可能相等。
th="555" height="213" src="file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml31280\wps10.jpg">tyle="font-family:calibri">
tyle="font-family:宋体">结论
tyle="font-family:宋体">本应用笔记介绍了使用驱动各种负载的时钟源的应用的正确终端技术。 它还概述了用于生成可靠应用程序设计的布局考虑因素 所有这些技术都力求最大限度地减少降低时钟信号的条件,从而导致系统性能不佳。

tyle="margin-top: 0px; margin-bottom: 0px; line-height: 1.5em;"> AT切割晶体单元使用厚度剪切模式作为主振荡模式,但还有许多其他寄生模式(弯曲振动,平面滑动振动等)。图1显示了AT切割晶体单元的振动模式。

tyle="margin-top: 0px; margin-bottom: 0px; line-height: 1.5em;"> 这些寄生模式的频率可以与特定温度下主振动的振荡模式的频率组合,从而影响振荡频率。
tyle="margin-top: 0px; margin-bottom: 0px; line-height: 1.5em;"> 当驱动电平对于规范来说太高时,杂散和主振动可能会耦合。图2显示了当驱动电平正常(驱动电平在标准范围内)和驱动电平过高(驱动电平超出标准范围)时,title="振荡器" target="_blank">振荡器频率温度特性如何不同。

tyle="margin-top: 0px; margin-bottom: 0px; line-height: 1.5em;"> 在电路研究中,我们提出了在驱动电平规范范围内的电路常数,以防止活动下降。

tyle="font-family:宋体">从早期的无线电到雷达,以及现在的数字计算,每个电路都需要一个时钟或心跳来指导其功能。时序控制从低功率到高精度的各种应用中的处理速率,数据连接和RF传输频带。时间已成为一个多元化的工程领域。考虑到可以设计时钟电路的多种方式以及每年引入该行业的许多进步,工程师应该定期重新考虑其时序考虑因素。以下是基本计时设备列表以及使用它们的最佳时间。
tyle="font-family:宋体">1.LC谐振器
tyle="font-family:宋体">LC谐振器是最简单和常用的定时电路,由放大器,电感器和电容器组成。主要优点包括低成本和易于集成,特别是在高频率下。然而,它不是非常准确,并且随温度变化很大。这种可变性提供了一个额外的属性:宽拉范围。因此,在开发小型或高度集成的压控振荡器(VCO)时,LC是首选的谐振器。这些振荡器在PCB或片上设计用于跟踪或锁定其他频率。由于温度可以使频率+/- 10,000 ppm或更高,因此LC不够精确,无法单独运行。
tyle="font-family:宋体">2.title="陶瓷谐振器" target="_blank">陶瓷谐振器
tyle="font-family:宋体">陶瓷谐振器tyle="font-family:宋体">的主要优点是成本。如果您正在寻找最低成本和稳定的解决方案,那么这项技术可以帮助您实现这一目标。不要指望在整个温度范围内稳定性小于tyle="font-family:宋体">+/- 1000ppmtyle="font-family:宋体">。该谐振器成本低,但不能用于精确或甚至部分精确的定时。玩具,低端设备和低端tyle="font-family:宋体">MCUtyle="font-family:宋体">应用程序等通用应用程序可以摆脱这种不精确的程度。如果您需要更高的精度,其他谐振器将帮助您。
tyle="font-family:宋体">3.title="石英晶体" target="_blank">石英晶体
tyle="font-family:宋体">石英晶体因其自补偿温度稳定性,出色的初始精度和适中的成本而成为时间之王。作为谐振器,它具有高Q值,可实现极低的在线噪声。批量生产已经对这些设备的精度和成本进行了微调,因此价格适中的晶体现在可以实现+/- 20ppm至+/- 50ppm的总体精度。它具有出色的稳定性,是当今许多连接协议的理想时间基础,从Wi-Fi,Zigbee和蓝牙到汽车LIN / CAN,以太网,UART和工业应用。定时MCU和使用石英晶体的处理器提供的精度可以满足常见的连接协议。但是,有些协议需要更高的性能。晶体的精度可以提高。
tyle="font-family:宋体">4.title="石英晶体振荡器" target="_blank">石英晶体振荡器(XO)
tyle="font-family:宋体">石英晶体振荡器集成了振荡器芯片和石英晶体。它提供了石英的准确性和低噪声优势,但降低了电路板走线引起的可变性。在某些情况下,振荡器芯片还将基本石英频率乘以应用所需的频率。在非常低噪声的系统中使用XO而不是裸石英晶体是必要的,例如高速通信,光学互连,光学模块,测试和测量以及先进的RF应用。XO以高频率提供低噪声,这对于使用普通晶体来说是难以实现的。高性能系统中使用的顶级频率如100MHz,156.25MHz或312.5MHz需要使用XO提供的差分LVPECL,LVDS,HCSL或CML信号进行调理。
tyle="font-family:宋体">5.title="温度补偿晶振" target="_blank">温度补偿晶振(TCXO)
tyle="font-family:宋体">虽然XO提供缓冲和频率转换,但它们跟踪石英晶体毛坯的精度。若干通信和电信应用,例如点对点RF,GNSS / GPS,移动电话,LPWAN网关和其他精密RF连接系统,需要在整个温度范围内具有+/- 0.5ppm至+/- 2.5ppm的频率稳定性。Stratum III需要+/- 0.28ppm的稳定性。裸露的石英不够稳定,不易达到低于10ppm的稳定性。TCXO经历了一个制造流程,可以测量和校准其频率偏差。明显的缺点是成本。请记住,没有什么比终端系统中不可操作的数据链路更昂贵。
tyle="font-family:宋体">6.烤箱控制的title="晶体振荡器" target="_blank">晶体振荡器(OCXO)
tyle="font-family:宋体">OCXO可以达到几乎不可想象的精度水平+/- 0.1ppm至0.1ppb或更高的温度。TCXO技术不仅使用温度校准。OCXO通过添加二阶控制 - 石英毛坯的温度来实现稳定性。在启动时,OCXO将石英毛坯加热到比环境温度高约10度,并将温度控制在该水平,从而最大限度地减少温度扰动。在许多情况下,OCXO还具有机械防护冲击和振动功能,使终端系统能够实现最大时钟精度以满足要求。与军用和雷达相关的许多应用以及用于移动电话的基站收发信台(BTS)需要这种精确度。快速移动车辆中的先进高精度GPS也需要高精度。
tyle="font-family:宋体">7.微电子机械系统(MEMS)
tyle="font-family:宋体">MEMS技术与石英并行发展。MEMS基于硅而非石英晶体,具有小型化和抗冲击和振动的优点。由于与MEMS谐振器相关的复杂性,MEMS的主要缺点是成本。虽然它可以用于晶体,XO和TCXO涵盖的各种应用中,但是当需要高耐久性时,MEMS是最佳的。此外,在尺寸为1.6 x 1.2mm的超小尺寸下,MEMS与晶体竞争非常激烈。可穿戴设备,无线充电板,工业控制,机器人,无人机和AR / VR等应用可以充分利用MEMS的耐用性和尺寸。

一般来说单相输出称之为晶体振荡器,并以正弦波或者CMOS波型(矩型波)输出为主要代表.
剪切的正弦波输出具有类似圆角矩形的波形,并常用于RF电路,因为它抑制了不必要的谐波.TCXO(温度补偿晶体振荡器)被称为削波正弦波输出的产物.由于CMOS波输出是对应于数字信号处理的逻辑电子的信号输出,所以有利于数字信号的传送,并用于时钟,如CPU等.
