晶振频率在:1.00-200.00MHz之间，目前市场上经常用到的频率较多的是 2.5MHz,3.2MHz,4.608MHz,4.096MHz,5MHz,5.12MHz,6.4MHz,6.5MHz,6.72996MHz,8.192MHz,9.216MHz,10MHz,10.24MHz,12MHz,12.24MHz,12.288MHz,12.8MHz,13MHz,14.4MHz,14.7456MHz,14.85MHz,16MHz,16.32MHz,16.368MHz ,16.384MHz,16.8MHz,17MHz,18.432MHz,19.2MHz,19.44MHz,19.68MHz,19.7985MHz,19.8MHz,20MHz,20.46MHz,20.48MHz,20.82857MHz,24MHz,24.576MHz,25MHz,25.6MHz,26MHz,26.451788MHz,27MHz,29.952MHz,32MHz,32.768MHz,33MHz,36.864MHz,38MHz,38.88MHz,40MHz,50MHz,61.44MHz,77.76MHz,100MHz,120MHz,122.88MHz,140MHz,160MHz,180MHz,200MHz等等。常规频率一般晶振工厂一级代理商都有较多现货，方便采购和比价。因此有经验的电路工程师在设计电路时，现咨询台湾鸿星晶振代理商南京鼎魁科技，这样对与降低产品批量生产时的采购成品和供货安全是非常有好处的
