Jauch CRYSTAL QUARTZ,Rhythmus und Energie - die Krafte, die die Welt bewegen und vorantreiben. Unsere Welt bei Jauch wird ganz besonders von diesen Impulsen gepragt. Denn Frequenzbauteile und Batteriela sungen bestimmen unseren Alltag und geben bei uns taglich den Takt und die Energie vor. Darüber hinaus sind es aber vor allem unsere Mitarbeiter, die Jauch zu einem ganz besonderem Unternehmen machen.

In unserem Blog nehmen wir Sie mit auf eine Reise über unsere Produkte, Mitarbeiter und die Jauch-Unternehmenskultur und geben Ihnen spannende Einblicke hinter die Kulissen der Jauch-Gruppe. Wir freuen uns darauf, mit Ihnen in Dialog zu treten!

節(jié)奏和能量 - 推動(dòng)和推動(dòng)世界的力量。我們?cè)贘auch的世界特別受到這些沖動(dòng)的影響。因?yàn)轭l率元件和電池解決方案決定了我們的日常生活,并為我們提供了每一天的節(jié)奏和能量。此外,它主要是我們的員工,使Jauch一個(gè)非常特殊的做企業(yè)。

在我們的博客中,我們將帶您了解我們的石英晶振產(chǎn)品,員工和Jauch企業(yè)文化,并讓您深入了解Jauch集團(tuán)的幕后故事。我們我們期待著與您進(jìn)行對(duì)話(huà)!

每個(gè)應(yīng)用都有頻率偏差容差預(yù)算，即使在最差的情況下也必須遵守，以確保應(yīng)用正常工作。因此，開(kāi)發(fā)人員必須了解可能導(dǎo)致頻率偏差的所有因素。這些因素的所有最壞情況的總和不得超過(guò)應(yīng)用的極限。

石英諧振頻率頻率偏差的可能原因有:

25°C時(shí)的頻率容差
溫度范圍內(nèi)的頻率穩(wěn)定性
長(zhǎng)期老化
電路的C不匹配L
CL負(fù)載電容容差引起的誤差

開(kāi)發(fā)人員必須將這些偏差的總和與他的應(yīng)用程序的公差預(yù)算進(jìn)行比較，并采取任何必要的糾正措施。

長(zhǎng)期老化因素

振蕩晶體諧振頻率的長(zhǎng)期變化稱(chēng)為老化。

老化過(guò)程發(fā)生在每個(gè)組件中。盡管石英晶體Quartz crystal在最終調(diào)整和密封前經(jīng)過(guò)復(fù)雜的干燥過(guò)程，然后在惰性氣體下密封，但導(dǎo)電膠中的微量溶劑和微量氧氣仍留在元件中，并在元件中長(zhǎng)期反應(yīng)。這種反應(yīng)導(dǎo)致石英上永久的頻率變化，稱(chēng)為長(zhǎng)期老化。

在計(jì)算容差預(yù)算時(shí)，開(kāi)發(fā)人員必須將應(yīng)用程序生命周期中的頻率變化考慮在內(nèi)。在個(gè)別情況下，標(biāo)準(zhǔn)石英的通常長(zhǎng)期老化率在頭十年高達(dá)+/-20ppm。這是一個(gè)飽和過(guò)程，在更高的溫度下會(huì)加劇，因此會(huì)更早生效。Jauch CRYSTAL QUARTZ.

Each application has a tolerance budget in terms of frequency deviation that must be adhered to even in the worst case scenario in order to ensure that the application functions. Developers must therefore be aware of all factors that can lead to frequency deviations. The sum of all worst-case scenarios of these factors must not exceed the limits of the application.

Possible causes of frequency deviations of a quartz resonance frequency are:

Frequency tolerance at 25°C
Frequency stability over temperature
Long-term aging
Mismatch of the circuit’s CL
CL error due to load capacitor tolerance

The developer must compare the sum of these deviations with his application’s tolerance budget and take any necessary corrective action.

Long-term aging factor

The long-term change in the resonant frequency of an oscillating crystal is called aging.

Aging processes take place in every component. Although the quartz crystals are dried in a complex process before final adjustment and sealing, and then sealed under inert gas, minute amounts of the solvents in the conductive adhesive and minute amounts of oxygen remain in the component, where they react over the long term. This reaction leads to a permanent frequency change on the quartz, which is called long-term aging.

The developer must take this frequency change over the lifetime of the application into account when calculating the tolerance budget. The usual long-term aging rate for standard quartz is up to +/-20ppm in the first ten years in individual cases. This is a saturation process that intensifies at higher temperatures and thus takes effect earlier.

Pre-aging for improved overall performance

Many applications require high frequency accuracy. For such applications (LAN, Wi-Fi, Bluetooth, etc.), severe long-term aging is not acceptable. That is why Jauch has developed special quartz crystals that have been optimized specifically for such applications. Along with many other improvements, these WA (wireless application) crystals are artificially pre-aged during production by intermediate storage in temperature chambers, thus greatly reducing aging to a maximum of +/-7ppm over 10 years in the application.

WA-Crystals from Jauch are very well suited for applications that require a smaller tolerance budget.

By using such WA crystals from Jauch, the developer can avoid problems caused by severe long-term aging in his application in advance. The devices are thus very well suited (along with a number of other optimizations) for use in wireless and networking applications that require a smaller tolerance budget.
