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.
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.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.

Abracon ClearClockTM晶體振蕩器系列解決方案，由于不斷增加的時(shí)鐘抖動(dòng)，系統(tǒng)設(shè)計(jì)者面臨著與參考時(shí)鐘抖動(dòng)相關(guān)的基本挑戰(zhàn)需要更小的形狀因子：隨著參考振蕩器內(nèi)石英晶體的尺寸減小，保持優(yōu)異rms抖動(dòng)性能的能力變得具有挑戰(zhàn)性。隨著不斷的需求無論是系統(tǒng)的整體尺寸還是功能，設(shè)計(jì)者都在尋找滿足最佳要求的參考時(shí)鐘小尺寸收斂和抖動(dòng)性能。
從一開始，Abracon就專注于始終如一地實(shí)現(xiàn)這種融合以微型形狀因子生產(chǎn)超低均方根抖動(dòng)時(shí)鐘解決方案。2018年，Abracon推出了兩款ClearClockTM系列下的解決方案，5x3.2mm和5x7mm封裝的AX5和AX7系列有源晶體振蕩器，分別地這些設(shè)備基于復(fù)雜的PLL技術(shù)，如圖1所示卓越的均方根抖動(dòng)性能–通常在載波12kHz至20MHz范圍內(nèi)優(yōu)于150fs。
在上述PLL方法中，采用了一些技術(shù)來提高相位噪聲的限制檢測(cè)器底板，使相位噪聲斜率提高了收斂性——進(jìn)一步遠(yuǎn)離載波。AX5和AX7設(shè)備經(jīng)過優(yōu)化，可滿足50MHz和2.1GHz載波之間的市場(chǎng)需求頻率。這些設(shè)備可以配置為之前指定的Abracon的生產(chǎn)設(shè)施。憑借提供業(yè)界領(lǐng)先的頻率上限的能力，AX5和AX7解決方案非常適合需要大于200MHz時(shí)鐘的應(yīng)用參考.
Abracon進(jìn)一步認(rèn)識(shí)到，對(duì)需要100至200MHz時(shí)鐘的客戶的需求日益增長(zhǎng)與基于PLL的AX5和AX7設(shè)備相比，具有更小形狀因數(shù)的解決方案。這些要求是通常以PCI Express（PCIe）、光收發(fā)器、數(shù)據(jù)存儲(chǔ)和網(wǎng)絡(luò)設(shè)計(jì)為中心。
作為回應(yīng)，Abracon推出了第三泛音ClearClockTM OSC振蕩器解決方案：AK2、AX3、AK5和AK7系列這些設(shè)備使用更安靜的架構(gòu)，實(shí)現(xiàn)卓越的超低均方根抖動(dòng)性能和業(yè)界領(lǐng)先的微型封裝能效.
例如，2.5x2.0x1.0mm AK2 ClearClockTM提供盡可能低的外形典型的均方根抖動(dòng)性能為117fs@156.25MHz，LVDS輸出格式為+2.5V偏置在遠(yuǎn)離載波的12kHz到20MHz帶寬上，最大保證抖動(dòng)性能為200fs。（見圖2。）
AX3 ClearClockTM有源晶振采用3.2 x 2.5 x 1.0 mm封裝，可提供低于80fs的典型均方根抖動(dòng)在156.25MHz載波上，LVPECL輸出格式的+3.3V偏置。（參見上一頁的圖3。）
第三泛音設(shè)備性能的秘訣在于其架構(gòu)的簡(jiǎn)單性。精心設(shè)計(jì)第三泛音晶體空白，連同所需載波信號(hào)的適當(dāng)捕獲，確保在感興趣的載波上具有出色的均方根抖動(dòng)性能。
