In principle, both quartz crystals and quartz oscillators are equally suitable. Both are capable of achieving the required frequency stability.

原则上，石英晶体谐振器和石英晶体振荡器同样适用。两者都能够实现所需的频率稳定性。

Where the application involves large volumes, quartz crystals are generally chosen for commercial reasons. However, many tasks are involved at the development stage in order to ensure that the result is a stable, reliably functioning product. In contrast to this is the costlier oscillator, which comes with its manufacturer’s guarantee that all parameters are met. This option offers maximum precision, coupled with high operational reliability – and all this with relatively little development outlay.

在应用涉及大量应用的情况下，出于商业原因，通常选择石英晶体谐振器。然而在产品开发阶段，由于涉及诸多工程任务以确保结果是稳定、可靠运行的产品，晶体振荡器为更好的选择，因为它无需额外的电路匹配，可以保证满足芯片所有参数要求，如高频率精度和运行的高可靠性。

To be able to fulfill all the demanding requirements placed on a precise quartz clock signal, special quartz crystal series have been created such as the Genuway SMD2016 crystals for wireless applications (WA). The electrical parameters of these products have been particularly optimized, and thanks to special pre-treatment they exhibit a particularly low level of long-term aging.

为了能够满足对精确石英时钟信号的所有苛刻要求，我们研发了特殊的石英晶体系列，例如用于无线应用的SMD2016晶体。这些产品的电气参数经过特别优化，并且由于经过特殊的预处理，它们表现出特别低的长期老化水平。

Finally, mention should be made of the ‘tuning-fork’ quartz crystal (also known as clock crystal) that is often also used and normally oscillates at 32.768 KHz. Many ICs offer the option of connecting an additional crystal as a standby clock generator. This offers the possibility of allowing the high-frequency clock to rest during standby phases of the application, thereby reducing power consumption by the IC significantly. The IC continues meanwhile to run in parts at 32.768 KHz (such as Genuway SMD3215 crystals) and is thus able to return to power mode quickly. Owing to their relatively high temperature sensitivity, clock crystals are not regarded as a sufficiently precise clock for wireless applications. Thanks to their significantly lower current consumption of just a few µA, however, they are considered an ideal addition for the standby mode that is often required. This aside, these clock crystals are of course also suitable for all traditional real-time clock applications.

最后，应该提到“音叉”石英晶体（也称为时钟晶体），它也经常使用，通常以 32.768 KHz 振荡。许多 IC 方案提供该晶体作为备用时钟发生器的选项。这提供了允许高频时钟在应用的待机阶段休息的可能性，从而显着降低 IC 的功耗。同时，该 IC 继续以 32.768 KHz 的频率运行（例如 晶诺威科技产SMD3215晶体），因此能够快速返回正常供电模式。由于其相对较高的温度灵敏度，时钟晶体不被视为无线应用中足够精确的时钟。然而，由于其电流消耗显著降低，仅为几μA，因此被认为是经常需要的待机模式的理想补充。除此之外，这些时钟晶体也适用于所有传统的实时时钟（RTC）应用。
