低成本的ECS音叉晶體優(yōu)點(diǎn)，對(duì)于未知的一切充滿了好奇以及探險(xiǎn)精神的ECS公司，面對(duì)未知是巨大的挑戰(zhàn)，也是新的機(jī)會(huì)，為了能夠抓住機(jī)會(huì)，敢于不斷突破自我的ECS，利用自身的優(yōu)勢(shì)，針對(duì)于新興開發(fā)專注打磨高性能的石英貼片晶振，同時(shí)以追求高質(zhì)量的產(chǎn)品為榮，持續(xù)不斷優(yōu)化與改進(jìn)產(chǎn)品，使得其能夠做到快速滿足不同應(yīng)用程序的需求。

幾乎每個(gè)人都至少有幾件普通的家居用品，受到撞擊時(shí)會(huì)產(chǎn)生共鳴并產(chǎn)生頻率。如果你曾經(jīng)用你的叉子在酒杯邊上敲了一下來發(fā)表演講，你已經(jīng)在一個(gè)共振的表面上創(chuàng)造了一個(gè)頻率。

當(dāng)該表面是制造到一定尺寸的壓電石英晶體時(shí)，可以產(chǎn)生一個(gè)非常特定的頻率，這是設(shè)計(jì)界的工程師所熟知的:32.768kHz。這是音叉手表晶體的頻率，簡(jiǎn)稱a音叉.

音叉是一種產(chǎn)生32.768千赫頻率的裝置。這個(gè)頻率很容易被分割，以測(cè)量一秒鐘的脈沖或波。由于這種簡(jiǎn)單的數(shù)學(xué)計(jì)算，音叉被用于顯示日期和時(shí)間的產(chǎn)品中。

因此，振蕩器中使用的音叉晶體將計(jì)時(shí)解決方案帶到了人類的水平，因?yàn)檫@個(gè)頻率可以通過我們對(duì)時(shí)間的普遍理解來測(cè)量。雖然所有的晶體振蕩器都可以在給定的時(shí)間實(shí)現(xiàn)特定的功能，但是如果應(yīng)用程序要求用戶了解那個(gè)時(shí)間，那么音叉晶體提供所需的精度。

如何使用音叉晶體

1赫茲的頻率正好相當(dāng)于一秒鐘的脈沖或波。然而，1Hz的晶體必須非常大，使得這種晶體不適合小而有效的電子設(shè)備，如現(xiàn)在標(biāo)志性的石英手表。因此，在任何需要小封裝尺寸無源晶體和人機(jī)界面的應(yīng)用中音叉晶體為工程師提供高精度。

音叉手表晶體存在于許多電子產(chǎn)品中，我們通過它來跟蹤時(shí)間。然而，這并不僅限于可穿戴設(shè)備和物聯(lián)網(wǎng)設(shè)備中使用的時(shí)鐘顯示器。在振蕩器中使用音叉晶體時(shí)，考慮以下用例:

• 一個(gè)顯示，告訴我們一個(gè)文件何時(shí)被創(chuàng)建、下載、保存或打印，以及其他常見的個(gè)人計(jì)算機(jī)功能。
• 一種建筑管理系統(tǒng)(BMS ),記錄設(shè)施中發(fā)生的重要事件，以便設(shè)施管理者可以分析與時(shí)間相關(guān)的數(shù)據(jù)，如24小時(shí)內(nèi)的用電量。
• 一種電子設(shè)備，允許用戶在一定時(shí)間內(nèi)對(duì)功能進(jìn)行編程，以便在需要時(shí)發(fā)生事件。例如，辦公建筑中的自動(dòng)化HVAC功能音叉晶體在下班時(shí)間保存能量。
• 音叉晶體的優(yōu)點(diǎn)

值得注意的是，在上述每個(gè)用例中，時(shí)序解決方案電路板中使用的音叉晶體可能非常小。這對(duì)于設(shè)計(jì)電子產(chǎn)品的工程師來說是有利的，因?yàn)楦咝А⒏　⒊杀靖偷脑梢詻Q定是贏得合同還是被其他工程師的產(chǎn)品忽略。

音叉晶體還在很寬的溫度條件下提供穩(wěn)定的頻率。振蕩器中使用的音叉晶體將經(jīng)歷最小漂移典型使用案例(例如辦公樓和家庭)所需的溫度范圍。如果需要溫度補(bǔ)償，則領(lǐng)先的晶體振蕩器制造商可以包括溫度補(bǔ)償晶體振蕩器(TCXO)與電路板上的32.768晶體一起控制頻率漂移。

一般來說，用于定時(shí)解決方案的石英晶體振蕩器以可承受的價(jià)格提供高水平的精度和可靠性。此外，當(dāng)音叉晶體振蕩器或任何石英晶體元件用于車輛時(shí)，它們經(jīng)過加固處理，以確保在汽車經(jīng)歷的各種條件下的耐用性和有效性。

• Nearly everyone has at least a few common household items that resonate and create a frequency when struck. If you have ever tapped your fork on the side of a wine glass to make a speech, you have created a frequency on a resonating surface.

  When that surface is a quartz crystal manufactured to a certain size, you can generate a very specific frequency that is well known to engineers in the design community: 32.768kHz. This is the frequency of a tuning fork watch crystal, simply known as a tuning fork.

  A tuning fork is a device that creates a frequency of 32.768kHz. This frequency is easily divisible to measure a one-second pulse or wave. Because of this easy mathematical calculation, tuning forks are used in products that display date and time.

  Therefore, tuning fork crystals used in an oscillator bring timing solutions to the human level because this frequency can be measured by our universal understanding of time. While all crystal oscillators can make specific functions happen at a given time, if an application requires the user to understand that time, a tuning fork crystal provides the required precision.

  How Tuning Fork Crystals Are Used

  
  

  A frequency of 1 Hz is the exact equivalent to a one-second pulse or wave. However, a 1 Hz crystal would have to be very large, rendering this crystal unsuitable for small, effective electronic devices like the now-iconic quartz wristwatch. Therefore, in any application that requires a crystal with a small package size and a human interface, a tuning fork crystal provides high precision for engineers.

  Tuning fork watch crystals are found in many electronic products by which we track time. However, this is not limited to clock displays used in wearables and IoT devices. Consider the following use cases for tuning fork crystals when used in an oscillator:

  • A display that tells us when a document was created, downloaded, saved or printed, as well as other common personal computer functions.
  • A building management system (BMS) that records important events as they happen at a facility, so that facility managers can analyze time-dependent data, such as how much electricity is used in a 24-hour period.
  • An electronic device that allows the user to program functions for a certain time, so that events occur when desired. For example, automated HVAC functions in an office building use tuning fork crystals to preserve energy during off hours.
  • Advantages of Tuning Fork Crystals

  It is important to note that in each of the use cases described above, the tuning fork crystal used in a timing solution’s circuit board could be exceptionally small. This proves advantageous for engineers who design electronics because efficient, smaller, less cost-prohibitive components can make the difference between winning a contract or being passed over for another engineer’s product.

  Tuning fork crystals also provide a stable frequency under a wide range of temperature conditions. Tuning fork crystals used in oscillators will experience minimal drift of temperature ranges required for their typical use cases (e.g., office buildings and homes). If temperate compensation is required, a leading crystal oscillator manufacturer can include a temperature compensated crystal oscillator (TCXO) with a 32.768 crystal on a circuit board to control frequency drift.

  Generally speaking, quartz crystal oscillators used for timing solutions provide a high level of accuracy and reliability at an affordable price. Further, when tuning fork crystal oscillators – or any quartz crystal components for that matter – are used in a vehicle, they are ruggedized to ensure durability and effectiveness under a wide variety of conditions that automobiles experience.

  • Where to Find Tuning Fork Crystals

  Tuning fork watch crystals are readily available, once you have found the right manufacturer of quartz crystal components. Ensuring your team is working with a leading manufacturer is not a matter of preference, as there are counterfeit manufacturers that should be avoided because of the inferiority of their products. Engineers should consider these measurable characteristics when searching for tuning fork crystals at a frequency of 32.768, TCXO crystal oscillators and any other frequency-control solution:

  • The components you need should come from a network of authorized distributors to ensure that the product was built by a leading manufacturer.
  • The manufacturer should have a readily available archive of resources and tools – including a parametric search function – to provide the information you need to decide on the right product for your application.
  • A manufacturer that provides comprehensive engineering support is a trustworthy choice, as they offer this service to help you implement their components effectively and maximize your success in the marketplace.
  • Look for a manufacturer with multiple decades of experience. This indicator allows you to conclude that this business has succeeded – and continues to succeed – as a trusted manufacturer in the engineering community.
