石英晶体振荡器的超长时间老化性能研究
摘要
将提供长达1900天的延长老化测试结果，以深入了解石英晶体振荡器的长期漂移特性。将对结果进行讨论，以显示环境条件和功率开关循环变化的影响。
1.介绍
对几种类型的石英晶体振荡器进行了非常长时间尺度的老化测量，包括AT和SC切割烘箱控制晶体振荡器（OCXO）以及温度补偿晶体振荡器（TCXO）。）尽管每个OCXO在生产中都会老化，但通常只在满足老化率规范所需的时间段内收集数据。由于确定真正的老化性能需要很长的测试时间，TCXOs很少老化。通常无法获得大组振荡器长期老化性能的研究结果。

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。

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。
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.
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.
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.
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.
