SiTime demonstrates MEMS-based timing and synchronisation for 5G

June 12, 2018 // By Jean-Pierre Joosting
SiTime Corporation are demonstrating their innovative Elite Platform™ MEMS-based timing products for 5G at the International Microwave Symposium (IMS2018) this week.

Precision oscillators, based on the Elite Platform™ set new benchmarks in dynamic performance, environmental immunity and reliability for small cell, synchronous Ethernet and time synchronization. Leveraging SiTime’s revolutionary DualMEMS™ noiseless temperature sensing and TurboCompensation™ architecture, these devices deliver the most stable timing in the presence of common environmental hazards – airflow, temperature perturbation, vibration, shock, power supply noise and electromagnetic interference (EMI).

5G is expected to transform connectivity with significantly higher bandwidth and lower latency. These features, offered after network densification and infrastructure upgrades, are expected to enable a host of new services such as network slicing and virtualization, broadband everywhere, faster machine-to-machine connectivity as well as automated driver assistance systems (ADAS).  

In a dense 5G network that transmits at higher speeds, radio-to-radio time accuracy must be within 65 nanoseconds – 20 times better than 4G. MEMS-based timing products from SiTime enable this crucial requirement by ensuring synchronization in the toughest environment, such as in the presence of disturbers such as shock, vibration, rapid temperature changes, and extreme temperatures. Theses products do this while offering 20 times better reliability and one-fifth the power.

SiTime will showcase the Elite family of Super-TCXOs, including:

  • Demonstration highlighting the robustness of the Elite family – enabling 5G densification and operating under harsh operating conditions including rapid airflow, fast temperature transients, and vibration.
  • Dynamic performance of the SiTime oscillator, with DualMEMS technology, will be compared to the performance of a best-in-class quartz precision oscillator in side-by-side tests.


Patented architecture with DualMEMS, noiseless temperature sensing and TurboCompensation.
