晶(jing)體振蕩器(qi)與(yu)晶(jing)體諧振器(qi)的區別

石(shi)英晶體(ti)(ti)諧(xie)(xie)振(zhen)(zhen)器是(shi)一個諧(xie)(xie)振(zhen)(zhen)元(yuan)件(jian)(jian)，振(zhen)(zhen)蕩(dang)(dang)器是(shi)一套完(wan)整的(de)電路單(dan)元(yuan)，其(qi)中可(ke)以包(bao)括一些(xie)選頻(pin)元(yuan)件(jian)(jian)，但不是(shi)全部(bu)。諧(xie)(xie)振(zhen)(zhen)器還包(bao)括如陶瓷諧(xie)(xie)振(zhen)(zhen)器，LC 諧(xie)(xie)振(zhen)(zhen)器等。而晶振(zhen)(zhen)，是(shi)晶體(ti)(ti)振(zhen)(zhen)蕩(dang)(dang)器的(de)簡稱，它是(shi)用晶體(ti)(ti)諧(xie)(xie)振(zhen)(zhen)器和電路結合(he)構(gou)成的(de)振(zhen)(zhen)蕩(dang)(dang)器部(bu)件(jian)(jian)，尤(you)其(qi)是(shi)指用石(shi)英晶體(ti)(ti)做成的(de)振(zhen)(zhen)蕩(dang)(dang)器部(bu)件(jian)(jian)。另外(wai)，諧(xie)(xie)振(zhen)(zhen)器是(shi)無源(yuan)器件(jian)(jian)，需要外(wai)圍電路驅(qu)動其(qi)工(gong)作(zuo)，產生時(shi)鐘(zhong)輸出。振(zhen)(zhen)蕩(dang)(dang)器則是(shi)有源(yuan)器件(jian)(jian)，石(shi)英諧(xie)(xie)振(zhen)(zhen)器生產廠家，自身就有內置電路，提供(gong)較(jiao)穩定的(de)時(shi)鐘(zhong)輸出。

晶體諧振器的定義

晶體(ti)諧(xie)(xie)(xie)振(zhen)器(qi)就(jiu)是指產(chan)生(sheng)(sheng)諧(xie)(xie)(xie)振(zhen)頻(pin)(pin)(pin)率(lv)的電(dian)子元件(jian)，常用(yong)的分(fen)為石英晶體(ti)諧(xie)(xie)(xie)振(zhen)器(qi)和陶(tao)瓷(ci)諧(xie)(xie)(xie)振(zhen)器(qi).起(qi)產(chan)生(sheng)(sheng)頻(pin)(pin)(pin)率(lv)的作(zuo)用(yong)，具有(you)穩定，抗干(gan)擾性(xing)能良(liang)好的特點，廣泛(fan)應用(yong)于各種電(dian)子產(chan)品中，石英諧(xie)(xie)(xie)振(zhen)器(qi)現貨，石英晶體(ti)諧(xie)(xie)(xie)振(zhen)器(qi)的頻(pin)(pin)(pin)率(lv)精度(du)要高于陶(tao)瓷(ci)諧(xie)(xie)(xie)振(zhen)器(qi)，但成本也比陶(tao)瓷(ci)諧(xie)(xie)(xie)振(zhen)器(qi)高. 諧(xie)(xie)(xie)振(zhen)器(qi)重(zhong)要起(qi)頻(pin)(pin)(pin)率(lv)控制的作(zuo)用(yong)，所有(you)電(dian)子產(chan)品涉及頻(pin)(pin)(pin)率(lv)的發射和接收都需要諧(xie)(xie)(xie)振(zhen)器(qi)。  

目(mu)前諧振器的(de)類型按(an)照外(wai)形可以分為直插式(shi)和貼片式(shi)兩中(zhong)。   

石英晶(jing)體(ti)俗稱(cheng)水(shui)晶(jing)，成分(fen)(fen)SIO2，是重要(yao)的(de)壓電(dian)材(cai)料，石英諧振器(qi)，其主要(yao)特征是其原子(zi)或分(fen)(fen)子(zi)有規律排列，反映(ying)在(zai)(zai)(zai)宏觀上是外形的(de)對稱(cheng)性。在(zai)(zai)(zai)電(dian)場的(de)作用(yong)下，晶(jing)體(ti)內部(bu)產生應力而(er)形變，從而(er)產生機械(xie)振動，獲得特定的(de)頻率，利用(yong)它的(de)這種(zhong)逆壓電(dian)效應特性來**石英晶(jing)體(ti)諧振器(qi)。石英由于具備天然的(de)品(pin)質因(yin)子(zi)“Q”，這使得晶(jing)體(ti)能(neng)在(zai)(zai)(zai)整(zheng)個工作溫度和電(dian)壓范圍內都保持很高的(de)準確度和頻率穩定性。
