5G New Radio (NR)

Communications infrastructure is undergoing a complete overhaul, creating a denser 5G network and bringing equipment closer to the consumer. With higher frequencies, tighter channels, and shorter-range radios placed in less controlled environments, there will be an even greater demand on the timing solution. SiTime provides robust, easy-to-use MEMS precision oscillators and clocks that provide the resilience needed for the next generation of radios (5G NR).
