Time synchronization became important when networks started using time division duplexing (TDD). With the forthcoming rollout of 5G, very tight time/phase synchronization, along with frequency synchronization, will be essential for these networks to improve data throughput to support the demands of emerging applications such as autonomous driving, remote surgery, and more precise geolocation.
Actual time error analysis using real-time data is a complex and lengthy process to perform ranging from weeks to months. To help alleviate these issues, SiTime has developed Time Error Simulator software that simulates how much wander is generated by the instabilities of the local oscillator, provided that reference inputs are ideal and wander free. This tool enables quick simulation of time error under a variety of different system parameters and temperature profiles.
