SiTime timing solutions — The heartbeat of 5G™
5G is on the way to bring broadband speed over mobile networks. To support the future of 5G, communications infrastructure is undergoing a complete overhaul—creating a denser network, closer to the consumer and in less controlled environments. With shorter-range radios, higher frequencies, and tighter channels, there is 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 to 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.

Features & Benefits
What are customers saying?
“Our electronics must deliver the highest performance and reliability while working in harsh environments. SiTime’s MEMS timing solutions enable us to deliver this benefit to our customers.”
SC Moon
VP of R&D
DASAN Network Solutions
"SiTime's SiT5356 Super-TCXO enables a new class of wireless devices to communicate with a base station without having to be perfectly calibrated in a factory setting. Subscriber units can now dynamically remove frequency offset, improving channel performance on the fly as needed. The world-class stability of the SiT5356 means that the firmware can focus on other things - set and forget."
