SiTime timing solutions – The heartbeat of 5G™
5G communications infrastructure is 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. SiTime keeps everything in sync with greater dynamic stability. Our MEMS timing solutions deliver the performance needed to keep networks running, even under the most demanding conditions like extreme temperatures, rapid airflow, shock, vibration, and electromagnetic interference.
