Elite Precision Super-TCXOs
for 5G, Small Cell, and Time Synchronization
±100 ppb stability with frequency tuning
±1 ppb/C ΔF/ΔT at 10C/min ramp
0.1 ppb/g, vibration resistant
SiTime’s precision oscillators, based on the Elite Platform™ set new benchmarks in dynamic performance, environmental
immunity and reliability for small cell, synchronous Ethernet and time synchronization. Leveraging SiTime’s revolutionary
DualMEMS™ noiseless temperature sensing and TurboCompensation™ architecture, these devices deliver the most
stable timing in the presence of common environmental hazards – airflow, temperature perturbation, vibration, shock,
power supply noise, and electromagnetic interference (EMI).
