What is the choice for performance in critical applications, MEMS (Micro-Electro-Mechanical Systems) or quartz-based oscillators? MEMS-based oscillators have been available on the market since 2005. In the last 15+ years, a handful of companies have developed MEMS-based oscillators. Today, only a few remain and the leading MEMS-based oscillator manufacturer accounts for around 1% of the total timing market. Many frequency control manufacturers private label from both companies, with the exception of ECS who does not see any value in the practice.

When selecting the oscillator for your electronic devices or communications equipment, some of the timing considerations you need to think about are: system performance, system clocking, signal quality and reference signal sources. These are the critical parameters that will decide the performance level of your product.

You may have seen another video from a MEMS manufacturer comparing MEMS oscillators to stand alone quartz crystals. It is proven that any oscillator be it quartz, SAW, ceramic, or MEMS will always outperform any standalone resonator. So, a comparison of an oscillator to a crystal is not a true test of the oscillator’s performance. In this side by side comparison, we will look at and directly compare a quartz-based oscillator with a MEMS oscillator.

当讨论振荡器时，会出现同样的问题。关键应用、MEMS（微机电系统）或<a href="http://www.guanjiedz.com/OSCillatorCrystal.html" title="石英晶体振荡器" target="_blank">an style="color:#000000;font-size:18px">石英晶体振荡器an>a>的性能选择是什么？自 2005 年以来，基于 MEMS 的振荡器已经上市。在过去 15 年多的时间里，少数公司开发了基于 MEMS 的振荡器。如今，只剩下少数几家，领先的基于 MEMS 的振荡器制造商约占整个时钟市场的 1%。两家公司的许多频率控制制造商都是自有品牌，但 ECS 除外，ECS 在实践中没有任何价值。
