KDS关于振荡电路的讨论方法

石英振子是无源部件，无源晶振，因此会受到电源电压、环境温度、电路结构、电路常数、基板的布线图案等的影响。 大致分为正常动作和异常动作两种。 因此，设计振荡电路时，前提条件是使石英振子稳定且可靠地振荡。 确认后，将讨论频率精度、频率的可变量、调制度、振荡开始时间、振荡波形等以下项目。

彼得曼32.768K有源晶振的优势，Time requirements in modern metering applications have massively increased in the last few years. The usual requirement in modern metering applications is a time offset of 1 hour after 7 years. It should also be possible for the operating temperature range of the application to comply with this value. 1 hour max. after 7 years corresponds to a frequency tolerance of ±16 ppm absolute at 32,768 kHz. It is no longer possible for conventional 32,768 kHz oscillating crystals to meet these requirements.

On the one hand, this is because 32,768 kHz are only available with a frequency tolerance of ±10ppm at +25°C, on the other hand, the temperature stability over a temperature range of -40/+85°C is more then -180 ppm. Moreover, ageing of approx. ±30 ppm after 10 years must be taken into account when calculating accuracy. In the worst case, a 32,768 kHz crystal has a maximum frequency stability of +40/-220 ppm (including adjustment at +25°C, temperature stability and ageing after 10 years). External circuit capacitance must be able to compensate any systematic frequency offset caused by the internal capacitance of the oscillator stage of the IC to be synchronised and by stray capacitance. The selection of a layout without external circuit capacitance for the 32,768 crystal involves a great risk because the accuracy of the 32,768 crystal can neither be corrected nor adjusted to suddenly changing PCB conditions during series production. Initially, the intersection angle for the 32,768 crystal was designed for optimal accuracy in wristwatches, and not for most of the applications for which it is used nowadays.

In order to meet the highly accurate time requirements, we as a clocking specialist offer the series ULPPO ultra low power 32,768 kHz oscillator. This oscillator can be operated with each voltage within a VDD range of 1.5 to 3.63 VDC. The specified current consumption is 0.99 µA. The temperature stability of ULPPOs is ±5 ppm over a temperature range of -40/+85°C. Frequency stability (delivery accuracy plus temperature stability) is ±10 ppm, and ageing after 20 years is ±2 ppm. Thus the maximum overall stability of ULPPOs is ±12 ppm including the ageing after 10 years. These are industry best parameters.

No external circuit capacitance is required for the circuiting of the ultra small housing (housing area: 1.2 mm2). The input stage of the IC installed in the ULPPO independently filters the supply voltage. Compared to crystals, ULPPOs save a lot of space on the printed circuit board so that the packing density can be increased, and smaller printed circuit boards can be designed. The adjustment of the amplitude further reduces the power consumption of the ULPPO.

For space calculations, both external circuit capacitances for a crystal on the printed circuit board must also be taken into account. With its two external circuit capacitances, even the smallest 32,768 kHz crystal requires more space on the PCB than ULPPOs do.

Moreover, very small 32,768 kHz crystals have very high resistances which usually cannot be safely overcome by the oscillator stages to be synchronised because the oscillator stages of the ICs or RTCs to be synchronised have very high tolerances as well. Therefore, sudden response time problems in the field might occur which can be ruled out with ULPPOs. Thus, the safe operation of the application is possible with ULPPOs under all circumstances.

Oscillator stages consume a lot of energy to keep a 32,768 crystal oscillating. Usually, the input stage of the MCU can be directly circuited with the LVCMOS signal of the ULPPO (usually Xin). Thus the input stage of the MCU can be deactivated (bypass function) so that the energy saved can be used for the calculation of the system power consumption of the meter. Moreover, ULPPOs are able to synchronise several ICs at a time. Due to the very high accuracy of the ULPPO, less time synchronisations are required, which also saves system power.

Of course, ULPPOs can be used in any applications which require miniaturised ultra low power 32,768 kHz oscillators such as smartphones, tablets, GPS, fitness watches, health and wellness applications, wireless keyboards, timing systems, timing applications, wearables, IoT, home automation, etc. Due to the high degree of accuracy of 32,768 kHz oscillators, the standby time or even the hypernation time in hypernation technology applications can be significantly increased so that a high amount of system power can be saved due to the significantly lower battery-intensive synchronisation cycles. Thus the 32,768 kHz oscillator is the better choice compared to 32,768 kHz crystals. Ultra low power 32,768 kHz oscillators are available with diverse accuracy variations – see also the ULPO-RB1 and -RB2 series.

不断精进自我的优质制造商彼得曼公司，致力于开发大量高质量的产品，随着近几年来，现代计量应用的时间要求大幅提高。现代计量应用的通常要求是7年后时间偏移1小时。应用的工作温度范围也应符合该值。最多1小时。7年后对应于32，768kHz下16ppm绝对值的频率容差。传统的32，768 kHz振荡晶体不再可能满足这些要求。彼得曼32.768K有源晶振的优势.

一方面，这是因为32，768kHz仅在+25°C时具有10ppm的频率容差，另一方面，在-40/+85°C温度范围内的温度稳定性高于-180ppm。此外，老化约。计算精度时，必须考虑10年后的30ppm。最差情况下，32.768K有源晶振的最大频率稳定性为+40/-220 ppm(包括+25°C时的调整、温度稳定性和10年后的老化)。外部电路电容必须能够补偿由要同步的ic振荡器级的内部电容和杂散电容引起的任何系统频率偏移。为32，768晶振选择无外部电路电容的布局包含很大的风险，因为在批量生产期间，32，768晶振的精度既不能校正也不能调整以适应突然变化的PCB条件。最初，32，768英寸晶体的交叉角度是为手表的最佳精度而设计的，而不是为如今使用它的大多数应用而设计的。

通过无源晶体和分立元件构建自己的振荡电路对于更大的数量或如果IC不使用内部振荡器。可以选择Pierce或Colpitts振荡器。此外，还可以创建振荡器通过反相器电路的适当反馈（图2）。

大多数微控制器已经包含了时钟电路的基本组件。为了完成电路对于Pierce或Colpitts振荡器类型，只需要一个晶体和其他外部无源元件。应用微控制器的手册描述了必要的细节。为了最大限度地减少任何寄生效应，所有连接从微控制器到晶体电路应保持尽可能短。
在40MHz及以上的频率下，使用泛音晶体。这些泛音晶体需要一个特殊的过滤器电路，以便抑制基本模式。滤波电路由电容器和电感组成。如果过滤器省略，电路以其基本模式振荡（例如：预期48MHz的第三泛音晶体，电路以16MHz振荡）。带有泛音晶体的振荡器电路应该非常谨慎地进行尺寸和测试。
如果微控制器配备皮尔斯振荡器配置，晶体将连接到两个电容器，如如图所示。3（C1和C2）。对于4MHz以上的频率，不需要额外的串联电阻器，因为适当的串联电阻器通常将被包括在微控制器的逆变器级内。此外，高欧姆电阻器集成在微控制器内，以调整直流工作电压（图3中为1MΩ）。CS1和CS2包括输入以及微控制器的输出电容以及由PCB上的导电路径贡献的其他电容。通过外部电容器C1使整个电路电容适合于晶体CL的指定负载电容和C2：

示例：提供CL=16pF。假设CS1＝CS2＝12pF，外部电容器可以被评估为C1＝15pF和C2＝27pF。应考虑这些作为后续优化的初始值。C1小于C2，以便提高电路的启动性能。
如果频率与晶体的实际谐振频率匹配，则晶体电路处于最佳状态。实际晶体在其指定负载电容下的谐振频率可以在其测试记录中找到。
应在没有来自探头的任何反馈的情况下测量频率。这通常可以通过测量在微控制器的另一个端口处的频率。如果石英晶振晶体被电容器过载，则频率较小比要求的要大（否则会更大）。
如上所述，具有皮尔斯振荡器配置的微控制器可能需要外部串联电阻器对于低于4MHz的频率。串联电阻器RV将有助于抑制不必要的泛音，并调整内部振荡器到外部pi电路，该电路由C1、C2和晶体组成。串联电阻器RV可评估为如下：RV与电容器C2串联，因此起到低通滤波器的作用（图2）。C2的值应为假如通过选择RV，截止频率fT应在基频和第三泛音之间（方程式2和3）。格耶品牌SMD晶振如何构建振荡电路?

线性相位
滤波器家族，包括高斯滤波器、贝塞尔滤波器及其导数，都在频带边缘缓慢衰减，因此具有减小的或最小的延迟峰值。这些滤波器的圆形通带之所以出现，是因为当频率偏离标称中心频率时，功率被反射到源。因此，这些SAW滤波器的回波损耗在远离中心频率处较差。经典网络理论表明，对元素值变化的敏感性伴随着较差的回波损耗。因此，该系列要求对组件进行更严格的控制，并且延迟性能经常偏离理论预测。这种敏感性还导致制造成本增加。一般来说，如果极点的数量受到限制，这些设计的工作更具可预测性。

领先全球的KVG有源晶体振荡器型号系列曝光,导言

石英振荡器是一种产生高频交流电压的电路。作为频率决定元件,振荡器包含一个振动石英。石英振荡器以其频率精度和频率稳定性令人信服。在实践中,电路被广泛用作无线电设备、处理器和微控制器的时钟。因此,石英和石英振荡器被认为是数据传输和电信中频率控制的最重要组成部分也就不足为奇了。其主要优点包括高谐振性能、各种OSC振荡器和高频率稳定性。

例如,测量设备、卫星导航设备或电信设备等专业应用对嵌入式振荡器有很高的要求,例如频率稳定性好、相位噪声低、使用寿命长。为了实现这一目标,所使用的石英也必须具有改进的老化特性,以获得相应的整体性能。石英振荡器通常可分为以下几类:固定频率振荡器(XO)、电压控制振荡器(VCXO)、温度补偿振荡器(TCXO)或温度控制的“Oven Controlled Xtal Oscillators”OCXO。

石英振荡器(XO)

石英晶体振荡器的最简单形式是X-tal振荡器(XO)。一般来说,它由一个电动模板组成,充当倒置放大器。在反馈网络中,振动方块作为频率确定元件集成。当循环增益大于1时,振荡器从噪声中开始振荡到频率,在此频率中,整个循环的相位移取2π的倍数。

遥遥领先加高晶体振荡器极化有何影响?Are Crystal Oscillators Polarized?

In the world of electronics, crystal oscillators are indispensable components. They're found in everything from consumer electronics to telecommunications equipment, providing the precision timing necessary for these devices to operate correctly. But a question that often arises is: Are crystal oscillators polarized? Let's delve into this, while also discussing what a crystal oscillator does and its main advantages.

What Does a Crystal Oscillator Do?

A crystal oscillator is an electronic device that uses the mechanical resonance of a physical crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.

The crystal, usually quartz, oscillates or vibrates at a specific frequency when voltage is applied. This vibration is then converted back into a voltage at the same frequency, creating an incredibly stable and consistent signal that can be used for timing purposes.

Are Crystal Oscillators Polarized?

Polarity refers to the electrical property of having two oppositely charged poles - one positive and one negative. Components that are polarized must be connected in a certain way to function properly. However, crystal oscillators are not polarized. They can be connected in any orientation and will still function as expected.

The reason for this lies in how crystal oscillators work. The piezoelectric crystal within the oscillator vibrates when voltage is applied, regardless of the direction of that voltage. As such, there's no 'right' or 'wrong' way to connect a crystal oscillator – it will function correctly as long as it's properly connected to the circuit.

The Main Advantages of a Crystal Oscillator

Crystal oscillators offer several key advantages that make them widely used across various applications:

1. High Stability: Crystal oscillators generate signals with excellent frequency stability and precision, making them ideal for tasks that require accurate timing.

2. Wide Frequency Range: These oscillators can generate signals over a wide range of frequencies, providing flexibility for different applications.

3. Low Power Consumption: Due to their design, crystal oscillators consume relatively low power, which is beneficial for battery-operated devices.

4. Durability: Crystal oscillators are highly durable and resistant to environmental changes such as temperature and humidity fluctuations.遥遥领先加高晶体振荡器极化有何影响?

In conclusion, while crystal oscillators are not polarized, their role in providing precise and stable timing signals is crucial in the realm of electronics. With their high stability, wide frequency range, low power consumption, and durability, it's no surprise that crystal oscillators are a cornerstone of modern electronic devices.

释放音频晶体的力量:提升您的声音体验

介绍

在音频技术领域，一项引人入胜的创新出现了——音频晶体。这些非凡的晶体彻底改变了我们感知和体验声音的方式。在这篇博文中，我们将探索音频晶体的迷人世界，深入了解它们的功能、优势，以及它们如何改变了我们的音频格局。

了解音频晶体

音频晶体是一种特殊的部件，具有增强音质的独特性能。这些压电石英晶体经过精心设计，可在特定频率下共振，从而优化各种设备和设置的音频性能。通过利用这些晶体的固有特性，音频工程师可以释放声音再现的全部潜力。

音频晶体背后的科学

音频晶体根据压电原理工作。当某些晶体在机械应力下产生电荷时，例如受到振动或压力时，就会出现这种现象。通过战略性地将这些晶体融入音频系统，声波引起的振动可以有效地转换为电信号，从而实现更清晰、更身临其境的声音再现。

在传统的OCXO中，为了提高频率稳定性，环境温度的影响实际上是通过将整个振荡器封装在保持恒定高温的“烤箱”中而消除。像传统的OCXO往往体积大、价格高且耗电，Connor Winfield开发了OH300系列微型OCXO。

在微型OCXO中，微型恒温晶体振荡器保持在近似恒定的温度略高于规定的工作温度范围，例如，对于运行温度范围为-40°至+85°C。然后将整个组件视为TCXO和温度扫描在工厂进行，并且用校正曲线对每个设备进行编程。这导致振荡器在-40°至+85°C范围内的典型稳定性优于±50ppb。这意味着每个设备都经过了测试在温度室内的整个操作温度范围内。规定的工作温度我们的数据表是OCXO附近空气的数据表。因为恒温晶振没有严格的传统OCXO所要求的温度要求，它可以以较低的成本和更小的包装。
请注意，OCXO附近的热源可能会使电路板温度高于空气温度。如果OCXO的内部温度由于客户模块内的对流加热，OCXO将不再保持其稳定性。这个可以即使OCXO外部的空气温度仍低于OCXO的最大运行温度，也会发生温度.

什么是VCXO？

VCXO是一种晶体振荡器，其输出频率根据施加的控制电压而变化。VCXO压控晶体振荡器输出频率的变化以百万分之一(ppm)为单位，如果计算中包括稳定性和老化，则称为牵拉能力、总牵拉范围或绝对牵拉范围(APR)。VCXO由晶体和振荡器电路以及变容二极管和支持电路组成。石英的高品质因数允许小范围的频率牵引。它们还具有低抖动和低相位噪声的高性能。

VCXOs用于微调工作频率，通常与锁相环(PLL)配合使用。VCXO中的拉取能力可以变化。有些只需要50ppm的拉力，而有些可能需要数百ppm的拉力。VCXOs的一些应用包括电信、测试和测量以及广播设备。
