Timing Products Enable 5G Radio Synchronization

SiTime Corporation is ramping up production of its 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. Capable of operating in harsh environments, the components enable smaller, more densely-deployed radios on telephone poles, buildings, and lampposts, without sacrificing network service quality.  

Leveraging the company’s DualMEMS temperature sensing and TurboCompensation technologies, the SiT5356/7 MEMS Super-TCXOs deliver dynamic performance for timing stability in the presence of environmental stressors due to air flow, temperature changes, vibration, shock, and electromagnetic interference. They can be factory-programmed to many combinations of frequency, stability, voltage, and pull range. This programmability enables designers to optimize the clock configuration while significantly reducing the lead-time and customization costs associated with quartz TCXOs where each frequency is custom built. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

Features include a stability of ±100 ppb stability and a ±1 ppb/°C frequency slope (ΔF/ΔT) over -40°C to +105°C. Samples and production volume of Elite Platform Super-TCXOs are available now. Pricing is available upon request. For more details, checkout the SiT5356/7 Super-TCXO datasheets.
