Temperature-Compensated Oscillators (TCXOs) for 5G Radio Synchronization in Global Wireless Network

SiTime Corporation announced the delivery of volume production of its Elite Platform of temperature-compensated oscillators (TCXOs) for all timing solutions used in 5G Radio Synchronisation in Global Network. The TCXO offers 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. The new TCXOs will enable smaller, more densely-deployed radios on telephone poles, buildings, and lampposts, without sacrificing network service quality.

 

The TCXOs are optimized to deliver industry-leading performance of ±100 ppb stability and ±1 ppb/°C frequency slope (ΔF/ΔT) over -40°C to 105°C. Using SiTime’s unique DualMEMS temperature sensing and TurboCompensation technologies, the  SiT5356/7 MEMS Super-TCXOs feature dynamic performance for timing stability in the presence of environmental stressors due to air flow, vibration, shock, temperature changes, and electromagnetic interference. The TCXOs device comes with multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

 

Samples and production volume of Elite Platform Super-TCXOs are available now. Pricing is available upon request from SiTime.
