彼得曼32.768K有源晶振的優(yōu)勢(shì)，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.

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.遙遙領(lǐng)先加高晶體振蕩器極化有何影響?

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.

音頻晶體背后的科學(xué)

音頻晶體根據(jù)壓電原理工作。當(dāng)某些晶體在機(jī)械應(yīng)力下產(chǎn)生電荷時(shí)，例如受到振動(dòng)或壓力時(shí)，就會(huì)出現(xiàn)這種現(xiàn)象。通過(guò)戰(zhàn)略性地將這些晶體融入音頻系統(tǒng)，聲波引起的振動(dòng)可以有效地轉(zhuǎn)換為電信號(hào)，從而實(shí)現(xiàn)更清晰、更身臨其境的聲音再現(xiàn)。

汽車(chē)正在推動(dòng)這一趨勢(shì)——目前平均每輛非自動(dòng)駕駛汽車(chē)有100個(gè)傳感器，向30-50個(gè)微控制器發(fā)送信息，這些微控制器運(yùn)行大約100萬(wàn)行代碼，每天每輛汽車(chē)產(chǎn)生1TB的數(shù)據(jù)。豪華汽車(chē)的數(shù)量可能是這個(gè)數(shù)字的兩倍，而自動(dòng)駕駛汽車(chē)增加傳感器檢查的幅度要大得多。

“如果蘋(píng)果制造了一臺(tái)攪拌機(jī)，那就是它”——英美在線(xiàn)新聞門(mén)戶(hù)網(wǎng)站Mashable一針見(jiàn)血。談到美學(xué)和產(chǎn)品設(shè)計(jì)，攪拌機(jī)“米洛”，由立陶宛初創(chuàng)企業(yè)米洛電器,離庫(kù)比蒂諾的偉大偶像很近。

除了屢獲殊榮的設(shè)計(jì)，“米洛”背后的技術(shù)尤為突出。專(zhuān)利的“磁力空氣驅(qū)動(dòng)”技術(shù)是該應(yīng)用的核心。與其他類(lèi)似設(shè)備相比，“米洛”杯和基站僅通過(guò)磁力相互連接；這意味著從安裝在攪拌機(jī)底座上的發(fā)動(dòng)機(jī)到安裝在杯子里的葉片的動(dòng)力傳輸，100%是通過(guò)這種磁性連接實(shí)現(xiàn)的。

JXS32帶來(lái)精確的頻率

由于其創(chuàng)新技術(shù)，該公司自2016年成立以來(lái)，已從各種投資者那里籌集了約140萬(wàn)歐元。Jauch Quartz也做出了自己的貢獻(xiàn):JXS系列的兩個(gè)Jauch組件確保了“米洛”控制電子設(shè)備的精確計(jì)時(shí)。

Crystek低抖動(dòng)有源晶體振蕩器，全球頂尖供應(yīng)商之一的Crystek公司，也是一家高性能技術(shù)領(lǐng)域的全球領(lǐng)導(dǎo)者無(wú)線(xiàn)電頻率(radio frequency)微波和頻率控制工業(yè)，Crystek Corporation一直提供頻率產(chǎn)品，包括石英晶體、XOs(時(shí)鐘石英晶體振蕩器)、TCXOs(溫度補(bǔ)償晶體振蕩器)、VCO(壓控振蕩器)和VCXOs(壓控晶體振蕩器)等元器件，Crystek Corporation的廣泛產(chǎn)品包括各種終端市場(chǎng)，包括無(wú)線(xiàn)、微波無(wú)線(xiàn)電、電信、工業(yè)、企業(yè)、航空航天和政府部門(mén)。

許多工程師在設(shè)計(jì)振蕩器電路時(shí)，并沒(méi)有在石英晶體上花太多心思。對(duì)他們來(lái)說(shuō)，這是一個(gè)標(biāo)準(zhǔn)的功能，無(wú)論如何都會(huì)起作用。其實(shí)沒(méi)那么簡(jiǎn)單。

振蕩器電路決定著應(yīng)用的心跳，需要石英晶體和其它元件之間的仔細(xì)匹配。否則，所產(chǎn)生頻率的準(zhǔn)確性會(huì)受到影響，應(yīng)用甚至可能在現(xiàn)場(chǎng)失敗。

我們Crystek希望讓我們的客戶(hù)免受此類(lèi)問(wèn)題的困擾。因此，我們對(duì)客戶(hù)的振蕩器電路進(jìn)行詳細(xì)分析，旨在實(shí)現(xiàn)晶體和電路的最佳匹配。在這些所謂的“OSF試驗(yàn)”過(guò)程中檢查了以下三個(gè)參數(shù):

1)頻率精度

2)振蕩安全系數(shù)(OSF)

3)驅(qū)動(dòng)水平

頻率準(zhǔn)確度

振蕩器電路的主要任務(wù)是在整個(gè)應(yīng)用周期和所有環(huán)境條件下產(chǎn)生穩(wěn)定而精確的頻率。為了使總負(fù)載電容(CL)必須盡可能接近額定負(fù)載電容(額定CL)或理想地與之匹配。

因此，電路分析的第一步是確定總負(fù)載電容(CL)石英晶體在其兩端“看到”的。由于與電路的任何直接接觸都會(huì)使測(cè)量結(jié)果失真，因此測(cè)量是在不接觸的情況下進(jìn)行的，使用近場(chǎng)探頭放置在電路上方一小段距離處。然后將晶體從電路中焊接出來(lái)，用晶體網(wǎng)絡(luò)分析儀在標(biāo)稱(chēng)溫度下測(cè)量L.

總C的偏差越大L從名義上的CL晶體的頻率偏差越大。然而，通過(guò)檢查分析儀中的晶體，可以確定需要哪些校正來(lái)提高電路的頻率精度。

振蕩安全系數(shù)(OSF)

在第二步中，檢查OSC振蕩器電路的振蕩安全性。該術(shù)語(yǔ)描述了電路在所有可能的環(huán)境條件下快速可靠啟動(dòng)的能力。因此，分析的重點(diǎn)是電路中的電阻。

如圖1所示，電路中內(nèi)置了一個(gè)新的附加電阻(R Pot ),與石英串聯(lián)。然后逐步增加R電位計(jì)的電阻，直到振蕩停止。這種方法模擬“最差情況下的石英”，并揭示特定振蕩器電路中石英的最大容許阻抗。
