ECS展頻晶振 ECS-3225S33-250-FN-TR功能介紹和應(yīng)用

2022-05-10 09:31:27 

ECS晶振發(fā)展至今不管是生產(chǎn)工藝還是應(yīng)用都已經(jīng)非常成熟了，但是你真的了解過(guò)ECS晶振嗎？從我們熟悉的有源晶振、無(wú)源晶振到到晶體、振蕩器以及展頻晶振，這些名稱(chēng)怎么來(lái)的？要了解這些問(wèn)題還得從ECS晶振的本體——石英晶體講起；（實(shí)際上作為振蕩器不止有石英晶振，還有基于半導(dǎo)體的晶振以及陶瓷晶振。石英晶振因?yàn)榘l(fā)展時(shí)間長(zhǎng)，技術(shù)相對(duì)成熟以及使用廣，本文只圍繞ECS石英晶振來(lái)講。）

石英晶振的主要功能材料為水晶，即一種化學(xué)成分為二氧化硅（SiO2）的六角錐形結(jié)晶體。石英之所以成為諧振器的原材料，是由于它具有正（機(jī)械能→電能）、逆（電能→機(jī)械能）壓電效應(yīng)。如果沿石英晶片的電軸或機(jī)械軸施加壓力使晶片產(chǎn)生形變，那么垂直于這些軸的兩個(gè)表面則會(huì)產(chǎn)生電荷，這種現(xiàn)象稱(chēng)為正壓電效應(yīng)。如果在石英晶體兩個(gè)表面施加電場(chǎng)，則晶片在電軸和機(jī)械軸方向?qū)⒀由旎驂嚎s，這種現(xiàn)象稱(chēng)為逆壓電效應(yīng)?；谶@種特性，當(dāng)石英晶振置于交變電場(chǎng)中，晶體的體積會(huì)發(fā)生周期性的壓縮或拉伸，形成了晶體的機(jī)械振動(dòng)。當(dāng)交變電場(chǎng)的頻率等于晶片的固有機(jī)械諧振頻率時(shí)，晶片的機(jī)械振動(dòng)幅度最大，產(chǎn)生共振現(xiàn)象。
