Connor-Winfield晶振,TX214系列晶振,5032有源晶振由于石英貼片晶振在數(shù)字電路中的重要性,在使用和設(shè)計(jì)的時(shí)候我們需要小心處理,尤其要注意以下5點(diǎn)細(xì)節(jié)。
1. 貼片晶振內(nèi)部存在石英晶體,所以在受到外部撞擊或者跌落的時(shí)候容易造成石英晶體斷裂破損造成晶振失效。在設(shè)計(jì)的時(shí)候就要考慮晶振的可靠安裝以及位置盡量不要靠近板邊,設(shè)備外殼等等。
2.在手工焊接或者機(jī)器焊接的時(shí)候要注意焊接溫度,貼片晶振對(duì)溫度比較敏感,焊接時(shí)溫度不能過高,并且加熱時(shí)間盡量短。
3. 設(shè)計(jì)的時(shí)候盡量縮短貼片晶振部分的走線,石英貼片晶振走線和其他信號(hào)線之間保留盡量遠(yuǎn)的距離,并且推薦將晶振的外殼接地,這些措施都能更好的避免干擾。
4. 謹(jǐn)慎選擇C1、C2的容值。盡量按照廠家提供的推薦值設(shè)計(jì)。在滿足起振要求的前提下,C1、C2的取值可以盡量小,能縮短貼片晶振起振時(shí)間。
5.注意貼片晶振是否被過驅(qū)動(dòng),過驅(qū)動(dòng)會(huì)影響晶振使用壽命。如果用示波器測(cè)試發(fā)現(xiàn)晶振的輸出被削波,波峰波谷被削平,那么就要考慮貼片晶振是否被過驅(qū)動(dòng)??梢赃m當(dāng)調(diào)整R1限流電阻的阻值。直到輸出完整的正弦波。
