Pletronics普銳特MEMS器件與標準石英器件的區(qū)別
Pletronics普銳特MEMS器件,基于先進的微機電系統(tǒng)(MEMS)技術研發(fā),是一種將微型機械結構,電子元件以及信號處理電路集成在一個微小硅芯片上的新型頻率控制器件.其核心工作原理是通過在硅片上制造微小的諧振器,施加外部電壓后,微機械結構發(fā)生振動,利用壓電效應將機械振動轉換為穩(wěn)定的電信號輸出,從而為電子設備提供精確的時鐘頻率,涵蓋MEMS振蕩器,MEMS諧振器等全系列產品,可滿足不同場景的頻率控制需求.標準石英器件(主要指石英晶振,石英諧振器),則是依靠石英晶體的壓電效應實現頻率控制——石英晶體在受到交變電場作用時,會產生規(guī)律的機械振動,其振動頻率固定且穩(wěn)定,通過對這種振動的采集與處理,輸出穩(wěn)定的時鐘信號.作為傳統(tǒng)的頻率控制器件,標準石英器件已應用多年,技術成熟,廣泛應用于各類中低端電子設備.
