常用于晶振产品的当属电子产品，作为电子产品与晶振的关系，相当于第二个灵魂，也是元器件中缺一不可的配件，当下市场中最常用到晶振产品的就有手机，蓝牙，通信设备等领域，而晶振中又可分为进口晶振和国产晶振，进口晶振在价格上面没有太大优势，性能较于国产晶振更加出色.随着国家大力发展半导体和国内研发实力的提升，我们的有源晶振已不逊色于进口的顶级产品，甚至在某些地方还要更胜一筹。EPSON进口有源晶振价格趋势由什么决定?X1G005601006900

石英晶体振荡器的应用：1、石英钟走时准、耗电省、经久耐用为其最大优点。不论是老式石英钟或是新式多功能石英钟都是以石英晶体振荡器为核心电路，其频率精度决定了电子钟表的走时精度。石英晶体振荡器原理的示意所示，其中V1和V2构成CMOS反相器石英晶体Q与振荡电容C1及微调电容C2构成振荡系统，这里石英晶体相当于电感。振荡系统的元件参数确定了振频率。一般Q、C1及C2均为外接元件。另外R1为反馈电阻，R2为振荡的稳定电阻，它们都集成在电路内部。故无法通过改变C1或C2的数值来调整走时精度。但此时仍可用加接一只电容C有方法，来改变振荡系统参数，以调整走时精度。

EPSON进口有源晶振价格趋势由什么决定?X1G005601006900，根据电子钟表走时的快慢，调整电容有两种接法：若走时偏快，则可在石英晶体两端并接电容C。此时系统总电容加大，振荡频率变低，走时减慢。若走时偏慢，则可在晶体支路中串接电容C。此时系统的总电容减小，振荡频率变高，走时增快。只要经过耐心的反复试验，就可以调整走时精度。因此，晶振可用于时钟信号发生器。2、随着电视技术的发展，近 来 彩电多采用500kHz或503kHz的晶体振荡器作为行、场电路的振荡源，经1/3的分频得到15625Hz的行频，其稳定性和可靠性大为提高。而且晶振价格便宜，更换容易，也许会有人好奇，进口有源晶振价格趋势由什么决定呢，往往由于市场的需求量决定其当前的价值，所以产品成为稀缺，价格也会出现上涨趋势。
