时间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创建一个更密集的网络,更接近消费者,在控制较少的环境中。随着短程无线电,更高的频率,更紧密的渠道,有一个更大的需求对定时解决方案。

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
  • 自动驾驶车辆使用的关键连接可能会出现故障

SiTime有助于保持一切同步,提高准确性和稳定性。我们设计了MEMS计时解决方案,以提供保持网络基础设施运行所需的性能和可靠性,even under the most demanding conditions like extreme temperatures, rapid airflow, shock, vibration, and electromagnetic interference.

"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."
