广泛用于当今的无线通信系统。它们已成为手机和不断发展的无线PDA行业的重要组成部分。高端TCXO也是电信等行业的重要组成部分。
TCXO和简单晶体振荡器之间的主要区别在于,TCXO包含额外的电路,用于校正(补偿)晶体的频率与温度特性。图1描述了如何校正晶体的简单说明。附加补偿电路分为三大类:数字、模拟或模拟/数字组合。了解数字和模拟补偿之间的差异很重要,因为它们在某些情况下是不可互换的。
商品TCXO在-40ºC至+85ºC范围内提供+/-1.5ppm至+/-5ppm的频率稳定性,最标准的规格在-30ºC至+75ºC范围内为+/-2.5ppm。在0ºC至+70ºC范围内低于+/-1.5ppm的频率稳定性很难实现,因此属于高性能类别。

Crystek晶振振荡器都是基于ASIC的,用于大批量制造。由于使用了特定的ASIC,晶体振荡器公司无法提供任何定制,除了该系列范围内的频率。此外,所有这些小型TCXO实际上都是VCTCXO——也就是说,它们提供了一个用于电气调谐或偏差的引脚。
