3225mm小體積的無(wú)鉛SMD晶振編碼Q22FA23V0048216，晶振成了這個(gè)時(shí)代帶給我們最好的產(chǎn)品，在電子元器件行業(yè)，雖然分化并不算太明顯，能夠看到明顯的變化，同時(shí)又需要在變化中找到相對(duì)的平衡點(diǎn)，晶振對(duì)于電子產(chǎn)品的重要程度，也是不可或缺的存在，除了芯片這顆靈魂之外，必不可缺的心臟--晶振，相對(duì)來(lái)說(shuō)也是頗受市場(chǎng)的關(guān)注，當(dāng)新型的晶振產(chǎn)品推出必然能夠快速吸引用戶(hù)的眼球，可是晶振的作用，又需要我們做出一番功課才了解其的原理，如何選擇適合的晶振等等，都成了我們必須要面對(duì)的問(wèn)題，而晶振出色的性能同時(shí)也得到用戶(hù)的好評(píng)，隨之而來(lái)，值得我們關(guān)注的依舊是晶振有何作用。

1.為系統(tǒng)提供基本的時(shí)鐘信號(hào)。通常一個(gè)系統(tǒng)共用一個(gè)石英晶振，便于各部分保持同步，有些通訊系統(tǒng)的基頻和射頻使用不同的晶振，而通過(guò)電子調(diào)整頻率的方法保持同步。

2.晶振與鎖相環(huán)電路配合使用，以提供系統(tǒng)所需的時(shí)鐘頻率。如果不同子系統(tǒng)需要不同頻率的時(shí)鐘信號(hào)，可以用與同一個(gè)晶振相連的不同鎖相環(huán)來(lái)提供。

3225mm小體積的無(wú)鉛SMD晶振編碼Q22FA23V0048216，晶振是晶體振蕩器的簡(jiǎn)稱(chēng)，在電氣上它可以等效成一個(gè)電容和一個(gè)電阻并聯(lián)再串聯(lián)一個(gè)電容的二端網(wǎng)絡(luò)。電工學(xué)上這個(gè)網(wǎng)絡(luò)有兩個(gè)諧振點(diǎn)，以頻率的高低分其中較低的頻率是串聯(lián)諧振，較高的頻率是并聯(lián)諧振。由于石英晶體自身的特性致使這兩個(gè)頻率的距離相當(dāng)?shù)慕咏谶@個(gè)極窄的頻率范圍內(nèi)，晶振等效為一個(gè)電感，所以只要晶振的兩端并聯(lián)上合適的電容它就會(huì)組成并聯(lián)諧振電路。這個(gè)并聯(lián)諧振電路加到一個(gè)負(fù)反饋電路中就可以構(gòu)成正弦波振蕩電路，由于晶振等效為電感的頻率范圍很窄，所以即使其他元件的參數(shù)變化很大，這個(gè)振蕩器的頻率也不會(huì)有很大的變化。
