无源晶振与有源晶振
无源晶振是在电路中产生谐振频率的电子元件,它是典型的无源器件,在外围电路的驱动下,产生时钟输出。而有源晶振将直流电能转换为具有一定频率的交流电能,其构成的电路叫振荡电路,振荡器是有源器件,振荡器比谐振器多了一个控制电路。
陶瓷谐振器与石英晶体谐振器
陶瓷谐振器是一种用于在特定频率产生振荡的压电式陶瓷设备。制造这种设备所用的材料在生产过程期间会激发谐振特性。由于这种谐振特性是处于生产误差范围内 的,并且它的品质因数远远低于石英的品质因数,因此陶瓷谐振器所能提供的频率稳定性不如晶体谐振器。通常陶瓷谐振器用于对成本较低且对性能要求不高的场合。
优点:同晶体相比,陶瓷谐振器的成本只有晶体的一半并且尺寸较小。
缺点:同晶体相比,欠缺频率和温度稳定性。其精度较差,大概在1%至0.1%之间。
综述:陶瓷谐振器的典型初始精度在0.5%至0.1%范围内,老化或温度变化所致的漂移可能改变这一精度范围。廉价陶瓷谐振器的公差只有±1.1%,较高端 的汽车精度则分别为±0.25%和±0.3%。未来的应用在于汽车CAN(控制器局域网络)总线应用,工作温度为-40°C至+125°C。频率为200 KHZ至约1 GHZ的低成本陶瓷谐振器适用于对时序要求不严格的嵌入系统。陶瓷器件起动较快,一般体积小于石英器件。它们也更能承受冲击与振动。
