MEMS OCXO enables 5G equipment to be deployed anywhere, in any environment

 SiTime Corporation announced the Emerald Platform, a revolutionary precision timing solution that solves critical timing challenges for 5G infrastructure equipment. With the Emerald Platform, operators can deploy 5G equipment in harsh environments and reliably offer mission-critical services.

“Timing is potentially the single biggest point of failure in 5G systems and can impact performance, reliability, and revenue. 5G timing is a complex challenge for system OEMs, and requires a new approach beyond traditional, component-level methods that are in use today. To solve this, SiTime pioneered a systems approach with Emerald to help our customers achieve their highest level of performance and capability. By combining our revolutionary MEMS with programmable analog, innovative packaging and high-performance algorithms, we have created a solution that is up to 20 times better than what is currently available,” said Rajesh Vashist, CEO of SiTime.

SiTime’s Emerald Platform is the first MEMS oven controlled oscillator (OCXO) in the industry. OCXOs offer the pinnacle of performance in timing and are critical to the reliable operation of all communications networks. However, quartz-based OCXOs are extremely sensitive to environmental stressors such as vibration, temperature changes and shock, which can degrade network performance, reduce uptime, and impact mission-critical services such as advanced driver assistance systems (ADAS). SiTime’s Emerald OCXOs solve these problems.

Because of the sensitivity of legacy quartz OCXOs, customers have to take many precautions to ensure reliable operation. A key challenge is the board placement of the OCXO, which needs to be located far away from stressors such as heat and airflow-induced thermal shock. This results in increased routing complexity and potential signal integrity problems. Designers have also tried using specialized plastic OCXO covers for thermal isolation, which introduces additional manufacturing steps and production complexity. Emerald MEMS OCXOs eliminate all of these problems; they simplify design, reduce development time, accelerate revenue while improving system performance.

Samples of the Emerald MEMS OCXO SiT5711/12 are available now for qualified customers. Production quantities will be available in Q2 2019 and stocked at catalog distributors such as Digi-Key and Mouser.
