常用于晶振產(chǎn)品的當(dāng)屬電子產(chǎn)品，作為電子產(chǎn)品與晶振的關(guān)系，相當(dāng)于第二個(gè)靈魂，也是元器件中缺一不可的配件，當(dāng)下市場中最常用到晶振產(chǎn)品的就有手機(jī)，藍(lán)牙，通信設(shè)備等領(lǐng)域，而晶振中又可分為進(jìn)口晶振和國產(chǎn)晶振，進(jìn)口晶振在價(jià)格上面沒有太大優(yōu)勢，性能較于國產(chǎn)晶振更加出色.隨著國家大力發(fā)展半導(dǎo)體和國內(nèi)研發(fā)實(shí)力的提升，我們的有源晶振已不遜色于進(jìn)口的頂級(jí)產(chǎn)品，甚至在某些地方還要更勝一籌。EPSON進(jìn)口有源晶振價(jià)格趨勢由什么決定?X1G005601006900

石英晶體振蕩器的應(yīng)用：1、石英鐘走時(shí)準(zhǔn)、耗電省、經(jīng)久耐用為其最大優(yōu)點(diǎn)。不論是老式石英鐘或是新式多功能石英鐘都是以石英晶體振蕩器為核心電路，其頻率精度決定了電子鐘表的走時(shí)精度。石英晶體振蕩器原理的示意所示，其中V1和V2構(gòu)成CMOS反相器石英晶體Q與振蕩電容C1及微調(diào)電容C2構(gòu)成振蕩系統(tǒng)，這里石英晶體相當(dāng)于電感。振蕩系統(tǒng)的元件參數(shù)確定了振頻率。一般Q、C1及C2均為外接元件。另外R1為反饋電阻，R2為振蕩的穩(wěn)定電阻，它們都集成在電路內(nèi)部。故無法通過改變C1或C2的數(shù)值來調(diào)整走時(shí)精度。但此時(shí)仍可用加接一只電容C有方法，來改變振蕩系統(tǒng)參數(shù)，以調(diào)整走時(shí)精度。

EPSON進(jìn)口有源晶振價(jià)格趨勢由什么決定?X1G005601006900，根據(jù)電子鐘表走時(shí)的快慢，調(diào)整電容有兩種接法：若走時(shí)偏快，則可在石英晶體兩端并接電容C。此時(shí)系統(tǒng)總電容加大，振蕩頻率變低，走時(shí)減慢。若走時(shí)偏慢，則可在晶體支路中串接電容C。此時(shí)系統(tǒng)的總電容減小，振蕩頻率變高，走時(shí)增快。只要經(jīng)過耐心的反復(fù)試驗(yàn)，就可以調(diào)整走時(shí)精度。因此，晶振可用于時(shí)鐘信號(hào)發(fā)生器。2、隨著電視技術(shù)的發(fā)展，近 來 彩電多采用500kHz或503kHz的晶體振蕩器作為行、場電路的振蕩源，經(jīng)1/3的分頻得到15625Hz的行頻，其穩(wěn)定性和可靠性大為提高。而且晶振價(jià)格便宜，更換容易，也許會(huì)有人好奇，進(jìn)口有源晶振價(jià)格趨勢由什么決定呢，往往由于市場的需求量決定其當(dāng)前的價(jià)值，所以產(chǎn)品成為稀缺，價(jià)格也會(huì)出現(xiàn)上漲趨勢。
