SiTime Delivers Timing Products for 5G Radio Synchronization in Global Wireless Network

Highlights

  • SiTime delivers volume production of 105°C Elite Platform™ MEMS Super-TCXOs™ for synchronizing 5G and 4G+ radios that operate in harsh environments
  • SiTime enables smaller, more densely-deployed radios on telephone poles, buildings, and lampposts, without sacrificing network service quality

SANTA CLARA, May 14, 2019 – SiTime Corporation, a market leader in MEMS-based silicon timing system solutions, announced volume production of its award-winning Elite Platform of temperature-compensated oscillators (TCXOs) that provide high stability and dynamic performance at 105°C for IEEE 1588-based synchronization in 5G/4G+ radios and enable wireless service providers to begin their network overhaul.

SiTime 5G“5G is expected to revolutionize the data economy but first it is re-writing the rules for wireless network deployment,” said Piyush Sevalia, executive vice president of marketing at SiTime. “5G radios will be deployed in outdoor environments – on lamp posts, buildings, traffic lights – with exposure to heat and rapid temperature changes that can cause loss of radio synchronization, which can disrupt services like advanced driver assistance systems and telemedicine. Unlike other timing vendors, SiTime takes a systems approach to solve these problems. We optimize our SiT5356/7 Super-TCXO system of MEMS, analog, advanced packaging and temperature compensation to deliver industry-leading performance of ±100 ppb stability and ±1 ppb/°C frequency slope (ΔF/ΔT) over -40°C to 105°C. We believe that radios with SiTime’s Super-TCXOs will minimize disruptions to 5G/4G+ services and ensure a better user experience.”

Meeting 5G’s Tougher Timing Requirements

Radio synchronization is a crucial technology that enables 5G and 4G+ to maintain service quality and reliability. The use of eCPRI and distributed architectures in 5G and 4G+ networks, along with outdoor deployment, increases timing complexity for synchronization.
