Overview

Precise and accurate timing is needed for a wide variety of applications such as radar, instrumentation, network synchronization, GNSS, O-RAN and 5G networks. For over 70 years, these applications relied on oven-controlled oscillators (OCXOs) to provide a stable timing reference. Historically, these oscillators have a reputation of being unreliable, difficult to design with, and susceptible to environmental stressors, often performing in unexpected ways in the field. This class introduces SiTime Epoch OCXO platform that surpasses existing OCXO technology to deliver precise timing in real-world environments.
