SiTime & Intel collaborate on tiny, low-power MEMS timing solutions to meet the high-performance requirements of 5G 

As the world moves towards 5G, designers need precision timing solutions that keep time accurate despite harsh environmental conditions such as tower vibrations and temperature fluctuations. Microelectromechanical systems (MEMS) chip maker SiTime offers innovative timing solutions that can replace quartz crystal-based timing devices and claim to enhance system performance in the presence of stressors such as vibration, high temperature, and rapid thermal transients.

Precise MEMS Timing Solutions For 5G

SiTime and Intel have collaborated for integrating timing for Intel’s 5G multi-mode radio modems, as well as Intel’s LTE, millimeter-wave wireless, Wi-Fi, Bluetooth and GNSS solutions.

The collaboration is intended to solve critical timing challenges for 5G and to achieve high-performance throughput in Intel’s 5G multi-mode radio modem platforms.

According to the announcement, SiTime’s timing solutions provide unique advantages such as small size and low power consumption to maximize battery life.

“Our collaboration with SiTime on MEMS-based silicon timing solutions will help our customers build leading 5G platforms to best take advantage of the increased performance and capacity that the 5G NR standard brings,” said Dr. Cormac Conroy, corporate vice president and general manager of the Communication and Devices Group at Intel Corporation. “Intel’s modem technology and our collaboration with SiTime is helping to enable new mobile and consumer experiences, and enterprise and industrial use cases.”

To realize the transformation to 5G, networks must become faster, more agile, and much denser, utilizing more equipment. Systems will be deployed closer to connected devices and in uncontrolled locations such as on streetlamps, traffic lights, rooftops, stadiums, and parking garages. In these settings, 5G devices will be subject to environmental stressors such as vibration, high temperature, and rapid temperature changes.

The company noted that these stressors can disrupt the timing signal and result in network reliability issues, lower data throughput, and even connectivity drops.

SiTime said it’s MEMS timing solutions offer up to 20 times better robustness, reliability, and performance in the presence of such stressors, and are crucial to the successful deployment of 5G.
