首创可穿戴和物联网应用时间基准的微晶音叉谐振器CC7V-T1A-32.768k-7pF-20PPM-TB-QA，瑞士Micro Crystal AG的国际产品经理Markus Hintermann说:“RTC模块RV-3028-C7是时间基准领域的新里程碑。计时与具有行业最低功耗的备用电路相结合，扩展了恶劣条件下的自主性，并将成为可穿戴和物联网应用的首选时间基准。”

新的实时时钟模块RV-3028-C7树立了最低功耗的新标杆:3 V电源下40nA，室温下1ppm的高精度消除了制造过程中的任何校准。仅3.2x1.5x0.8mm的微小封装将贴片石英晶体与RTC电路结合在一起，还集成了电池备份开关。极低的功耗允许使用MLCC电容来覆盖备份时间。加上事件检测输入，它具备可穿戴设备、医疗保健和功耗敏感型物联网应用的所有先决条件。

ECS-8FA3X-250-TR是一款低损耗超小型的SMD振荡器，Mean Time Between Failure (MTBF) for MEMS is stated at 130,000 years, as compared to a quartz device stated at 30,000 years. On the surface a 4:1 ratio of improvement seems like a significant talking point until you consider most products are designed with a less than five-year life cycle. Typically, long life designs are in the ten to fifteen-year life cycle, with a very small group needing as much as twenty years. If you compare the jitter, phase noise, and temperature performance tradeoffs you lose when comparing MEMS versus quartz, you are giving up a tremendous amount of performance today so your product might last for 130,000 years. For reference: Humans have been around for 200,000 years. Civilization for a mere 6,000 years. I think we can all agree that 30,000 years is enough.

MEMS 的平均故障间隔时间 (MTBF) 为 130,000 年，而石英晶振器件为 30,000 年。从表面上看，4:1 的改进比例似乎是一个重要的话题，直到您考虑到大多数产品的设计生命周期不到五年。通常，长寿命设计的生命周期为 10 到 15 年，极少数设计需要长达 20 年。如果您比较在比较 MEMS 和石英时失去的抖动、相位噪声和温度性能折衷，那么您今天就放弃了大量的性能，因此您的产品可能会持续 130,000 年。供参考：人类已经存在了20万年。文明只有6000年。我想我们都同意三万年就足够了。

最新发布的DSC6000产品，带有CMOS ASIC不比谐振腔模具大多少，尺寸可达1.6 mm x 1.2mm。微芯片MEMS振荡器可靠性，机械冲击与振动测试结果符合MIL-STD-883显示与传统石英相比，性能有所提高技术。可靠性数据，经过几个编译多年的生产，显示出令人印象深刻的FIT, MTBF可靠性和dppm质量水平。
