美國艾博康A(chǔ)BRACON晶振結(jié)合內(nèi)置電路石英的適當(dāng)匹配ABS07-120-32.768KHZ-T

如今,大多數(shù)電子電路都基于時(shí)鐘邏輯(包括微處理器、微控制器、FPGAs和CPLDs),需要一個(gè)時(shí)鐘源.根據(jù)頻率精度要求,有些采用諧振器,有些則使用現(xiàn)成的石英晶體結(jié)合內(nèi)置諧振器電路；嵌入在大多數(shù)微控制器和微處理器.

Abracon Crystal晶振大多數(shù)(如果不是全部)嵌入式解決方案使用Pierce諧振器配置,集成為SOC(片上系統(tǒng))的一部分.明顯的事實(shí)與獨(dú)立諧振器相比,優(yōu)點(diǎn)包括成本、尺寸和功率；雖然關(guān)鍵的限制是石英的適當(dāng)匹配內(nèi)置皮爾斯諧振器的晶振美國艾博康A(chǔ)BRACON晶振,ABS07-120-32.768KHZ-T

從晶體來看,環(huán)路電容主要影響整體諧振器環(huán)路電容.該有效環(huán)路電容決定了諧振器環(huán)路相對(duì)于所需的諧振距離共振頻率.然而,整體的長期表現(xiàn)貼片晶振諧振器環(huán)路受以下因素影響:這些環(huán)路電容的無功阻抗(Xc)逆變器放大器的跨導(dǎo)(gm)限流電阻(Rs)是否存在美國艾博康A(chǔ)BRACON晶振,ABS07-120-32.768KHZ-T
