Bliley如何防止BTCS3-16MHZMCN-BCCT晶体振荡器中的频率扰动？

频率扰动也称为活动骤降，很难在晶体振荡器中发现。但一个小小的干扰就可能导致应用信号出现重大问题，包括在GPS或导弹系统中。

想象一下发射一枚导弹，然后失去对其导航的控制。或者得到一个非常不准确的飞机GPS速度读数。这些（以及许多其他问题）可能是由于未能发现晶体中的活性下降而引起的。

在本文中，我们将帮助您理解什么是频率扰动以及如何防止频率扰动在石英晶体振荡器中发生。

NEL is a ISO 9001-2008 certified company and has a strong industry reputation for high reliability with its products.

Breakthrough Synchronized Crystal Oscillator, SXO

NEL’s synchronized crystal oscillator (SXO) technology offers significant performance advantages for high performance computing requirements. Parallel processing applications that require scalable synchronized clocking now have a better solution than the traditional clock distribution approach. The Synchronized Crystal Oscillator provides:
• Frequency and phase synchronization among an unlimited number of clocks in an HPC timing architecture
• Redundancy—Eliminates the need for master clock resulting in no single point of clock failure risk
• Full scalability—Additional SXO’s can be added (synched) to an existing SXO ensemble
• Reduced system level jitter—Additive jitter associated with clock distribution is eliminated
SXO evaluation boards, white paper, and demonstrations are available upon request.

Lowest Phase Noise Solutions Available

NEL Frequency Controls can optimize crystal oscillator phase noise performance based on customer goals and requirements. Customers looking for a competitive advantage with their application’s phase noise performance will often choose NEL to help gain a performance advantage of -5 dBc/Hz to -10 dBc/Hz. Customers looking for low cost ways to upgrade existing designs and platforms turn to NEL for the flexibility of selecting varying levels of phase noise performance within a drop-in compatible package.

Problem Solving

The crystal oscillator is often described as the heart of the system. Having an optimized frequency control solution for an application requires an understanding of the environment in which the crystal oscillator will be operating. NEL engineers are adept at providing robust solutions that factor in signal integrity issues, such as power supply noise, harmonics, shock and vibration, loading, temperature, and assembly conditions.

As a supplier of frequency control products, RubyQuartz Technology, LLC uses certain minerals in the products we manufacturer. While Raltron requires all our suppliers to comply with the Electronics Industry Code of Conduct and to only source materials from environmentally and socially responsible suppliers, we recognize the complex supply chain involved with certain minerals and have taken steps to ensure that virgin metals we purchase do not originate in conflict mines. ‘Conflict Mining’ or ‘Conflict Metals’ or ‘Conflict Minerals’ refers to the illegal control of some mines in the eastern region of the Democratic Republic of Congo in Africa. The electronics industry uses certain types of metals, some of which are potentially refined from minerals obtained from these mines.

The primary minerals and metals that could potentially come from conflict mines are:

• Cassiterite (tin)
• Gold
• Cobalt
• Coltan (tantalum)
• Wolframite (tungsten)
• Pyrochlore (niobium)

The metals that RubyQuartz Technology, LLC uses are tin and gold. Tin is used in certain copper alloy terminals, some platings, and solder, while gold is used in platings of some terminals and gold electrodes. Tungsten is also used in the making of the ceramic packages used in SMD components.

RubyQuartz Technology, LLC does not directly purchase any of the other minerals and metals listed (cobalt, niobium, and tantalum), so we are focusing our efforts on tin and gold suppliers.

RubyQuartz Technology, LLC requires all our suppliers to conform to the Electronics Industry Code of Conductbecause the supply chain for these minerals is complex, Raltron has requested that our tin and gold suppliers, trace these metals to their source, and to take corrective actions if any conflict mines are used. Raltron and its suppliers do not knowingly use any virgin tin or gold obtained from conflict mines and will regularly query suppliers to verify our requirements are being met to help ensure the health and safety of all workers in our supply chain

在电子学中，晶体(通常由石英制成)用于振荡器中，以产生稳定的工作频率。它们也用于滤波器中，以分离不同频率的信号。

HELE领先同行的石英晶体多方面应用

在Harmony Electronics，我们处于在各种行业中利用石英晶体元件的最前沿。我们的产品广泛应用于汽车、医疗、数据通信等领域。在这篇博文中，我们将深入探讨这些应用，特别关注石英晶体振荡器和石英晶体谐振器在汽车和医疗领域的应用。

汽车电子：用石英晶体元件推动创新

在汽车电子领域，石英晶体元件起着至关重要的作用。它们构成了晶体振荡器电路和晶体定时器等系统的主干，是许多汽车电子设备功能不可或缺的组成部分。

石英频率是汽车级晶体的关键因素，具有出色的稳定性和精度。例如，我们的OCXO(恒温晶体振荡器)和TCXO(温度补偿晶体振荡器)产品提供可靠和精确的频率控制，即使在变化的环境条件下。

此外，我们的32.768kHz晶体通常用于实时车辆时钟，有助于计时和事件记录等功能。我们的石英晶体组件也用于天线服务，确保车辆内部和车辆之间精确和一致的通信。

什么是雷达？
雷达(无线电探测和测距)使用无线电波来探测环境中的物体。它允许确定距离(称为范围)、角位置(方位)和速度。雷达技术是在第二次世界大战期间为军事用途开发的，但现在有许多民用应用，包括空中或海上交通管制、天文学、海洋和气象监测、测高、地质观测和汽车应用。

雷达系统包括一个发射机，它向某一方向发射电磁射频波(雷达信号)。目标物体反射的信号(回波)随后被雷达接收器检测到。反射的大小取决于物体的材料属性、大小和形状(雷达截面RCS)。通过处理这个反射信号，可以确定目标的特性。

DIODES晶体振荡器:为数字电子带来同步

在家里或工作中遇到的大多数电子系统将包括至少一个振荡器，该振荡器作为时钟工作，提供精确的定时、同步操作或作为频率参考。在这里，我们将了解使用石英晶体振荡器的诸多好处，并讨论可用的选择。

在基于微处理器的系统中有许多不同的时钟信号，用于执行指令、传送外部通信接口以及将数据移入和移出存储器。

虽然简单的嵌入式控制器的时钟频率可能在几兆赫左右，但PC的时钟频率通常预计为15兆赫，然后在内倍增，为CPU和其他子系统提供时钟。系统中的其他组件可能有自己的时钟要求，例如以太网控制器的25MHz时钟或实时时钟(RTC)所需的32.768kHz时钟。

此外，精确的频率参考是射频(RF)系统的先决条件，以便促进端到端通信，并确保滤除不受欢迎的噪声和信号。

面向物联网和智能家居应用的可靠电子元件

物联网(Internet of Things，简称IoT)是指任何远程连接到互联网的电子设备。物联网技术已经融入到我们现代世界的方方面面。电子系统被用于从计算机到工业制造工厂、农业科学的方方面面，甚至是运行家中最基本的设备，比如照明。其中许多技术依赖于他们通过台式电脑或其他移动设备(如智能手机，智能手环晶振，平板电脑)与操作员远程通信的能力。

可靠的电子元件

随着电子技术领域的迅速发展，越来越多的企业开始追逐市场份额。所有物联网设备设计中的高质量、可靠和坚固的电子元件确保了产品的寿命和整体客户满意度。

使用高质量电子元件设计的物联网设备具有长期、可靠的性能，最终将窃取市场份额。质量是关键，消费者在很大程度上根据产品评论做出购买决定。

什么是实时时钟？

实时时钟(RTC)是一种数字时钟，其主要功能是即使在电源关闭或设备处于低功耗模式时也能准确跟踪时间。RTC由控制器、振荡器和嵌入式石英晶体谐振器组成。它们被设计为一体式器件，提供比分立器件更好的性能，简化新设计中的集成，并加快上市时间。

RTC的功能称为寄存器。寄存器数据被编程写入RAM存储器。寄存器会定期更新，即使在正常RTC操作期间也是如此。RTC设计还包括电池供电的电源开关功能或另一个低功率备用电源。这样，即使设备进入睡眠模式或主电源断电，RTC也能保持精确和连续的时间计数。它还减少了用户在每次器件电源循环时重置时间和日期的需要。

ECS变频控制产品介绍

频率控制是保持数字设备时钟和时序稳定性的过程。今天所有的数字电路都需要时钟来确保进程以特定的时间间隔发生。

20世纪70年代，推出了数字手表。该设计使用kHz手表晶体来保持计时，这是我们今天仍在使用的工艺。实时时钟(RTC)在大多数处理器中用于计时，在寄存器中用作计数器。振荡器提供RF信号，TCXOs用于双向通信设备，以提供清晰的通信。

音叉晶体

水晶包装一天比一天小。目前，ECS Inc. International提供1.2x1.0毫米和1.6x1.2毫米的包装尺寸。在全球范围内，最常见的晶体封装尺寸为3.2x2.5毫米。32.768K手表晶体也变得越来越小，最常见的尺寸为3.2x1.5毫米或1.2x1.0毫米。虽然较小封装尺寸的销量每年都在增长，但降低BOM成本的需求往往是最重要的。因此，像我们的CSM-7X (5PX)这样的HC-49 SM包装仍然是全球最畅销的。晶体最常用于处理器。它们需要PCB上的匹配电容来构成振荡器环路。
