我们的32.768kHz晶体振荡器 (XO) 具有适用于各种应用的卓越性能。我们的产品包括世界上最小的 32.768kHz 晶体振荡器 (XO)，尺寸仅为 2.0 x 1.6 mm（KM 系列）。KM 系列旨在应对小型化的挑战，同时保持时序信号的卓越精度。我们还提供 KX 系列晶体振荡器，它们是业界功耗最低（小于 10 µA）和最严格稳定性 (+/- 20 ppm) 的 32kHz XO。
由于许多低功耗和便携式应用程序大部分时间都处于待机模式，因此这些系统必须最大限度地降低待机功耗。我们基于 32.768 kHz 的定时源允许这些系统快速转换到待机模式（<10ms），以最大限度地延长电池寿命，而不会牺牲维持准确时钟和日历所需的稳定性（± 20ppm）。

有源晶振是用石英晶体组成的，石英晶片之所以能当为振荡器使用，是基于它的压电效应：在晶片的两个极上加一电场，会使晶体产生机械变形；在石英晶片上加上交变电压，晶体就会产生机械振动，同时机械变形振动又会产生交变电场，虽然这种交变电场的电压极其微弱，但其振动频率是十分稳定的。当外加交变电压的频率与晶片的固有频率（由晶片的尺寸和形状决定）相等时，机械振动的幅度将急剧增加，这种现象称为“压电谐振”。KX251系列输出时钟信号与LVCMOS/LVTTL逻辑电平兼容,KX2513D0032.768000,2520mm晶振
