Infrastructure

A small part from SiTime runs a big part of your world

5G is on the way to bring broadband speed over mobile networks. To support the future of 5G, networking and telecom infrastructure is undergoing a complete overhaul – creating a denser network and bringing equipment closer to the consumer. With higher frequencies, tighter channels, and shorter range radios, there will be an even greater demand on the timing solution.

If timing fails

  • You experience dropped calls and slow web browsing on your phone
  • New services, such as instantaneous download of your favorite epic movie, will halt
  • Critical connectivity used by autonomous vehicles may fail

SiTime helps keep everything in sync with greater accuracy and stability. We’ve designed our MEMS timing solutions to deliver the performance and reliability that's needed to keep network infrastructure running, even under the most demanding conditions like extreme temperatures,  rapid airflow, shock, vibration, and electromagnetic interference.
