編碼ECS-2033-160-BN是一款具有核心競(jìng)爭(zhēng)力的超小性SMD振蕩器，振蕩器可以有幾種不同類型的與之相關(guān)的諧振器。其中最多產(chǎn)和表現(xiàn)最好的是石英晶振。您還可以找到使用基于陶瓷、SAW [1]或 MEMS [2]的諧振器的振蕩器作為工作頻率的起點(diǎn)。它們使用機(jī)械振動(dòng)或調(diào)諧腔來(lái)產(chǎn)生時(shí)鐘信號(hào)。在石英基振蕩器的情況下，石英材料的成分以及晶體切割的角度使得這種類型的振蕩器在很寬的溫度范圍內(nèi)非常精確和穩(wěn)定。制造振蕩器級(jí)晶體空白的過(guò)程非常耗時(shí)，需要許多步驟來(lái)確保始終如一的高質(zhì)量有源晶振產(chǎn)品，但它們提供的穩(wěn)定性比RC振蕩器要好得多。

編碼ECS-2033-160-BN是一款具有核心競(jìng)爭(zhēng)力的超小性SMD振蕩器，振蕩電路背后的原理是穩(wěn)定的穩(wěn)態(tài)輸出信號(hào)。實(shí)現(xiàn)此目的的一種方法是使用正反饋循環(huán)。在這里，輸出電壓的一部分被反饋到輸入，沒(méi)有凈相移，因此增強(qiáng)了輸出信號(hào)。然后信號(hào)被放大并再次環(huán)回，導(dǎo)致輸出信號(hào)增長(zhǎng)。反饋回路中的增益需要控制為單位增益，否則信號(hào)將被削波和失真。

Oscillators can have several different types of resonators associated with them. The most prolific and best performing of these is quartz. You may also find oscillators that use ceramic, SAW[1] or MEMS[2] based resonators to be the starting point for the operational frequency. They use mechanical vibration or tuned cavities to generate the clock signal. In the case of the quartz-based oscillator, the composition of the quartz material, and the angles that the crystal are cut makes this type of oscillator very precise and stable over a wide temperature range. The process for making oscillator grade crystal blanks is time consuming, with many steps to ensure consistent high-quality product, but they offer vastly superior stability over RC oscillators.

The principle behind the oscillator circuit is a stable steady state output signal. One way to accomplish this is by using a positive feedback loop. Here a portion of the output voltage is feedback to the input with no net phase shift, so reinforcing the output signal. The signal is then amplified and looped back again causing the output signal to grow. The gain in the feedback loop needs to be controlled to unity gain, otherwise the signal will be clipped and distorted.
