Ultra-low Power Fast Start OCXO


Clocking solutions need to meet the requirements of fast start-up and battery life of portable battery-powered devices such as portable wireless communications devices, mobile test equipment-level mobile precision positioning, etc. while ensuring the performance and stability. However, the power consumption of OCXO has been a problem in such application scenarios all along.
In this context, Dapu breaks through the bottleneck of OCXO’s power consumption technology based on nearly two decades of accumulation of independent core technology in high-stability crystal oscillators. By adopting advanced vacuum holder structure and exclusive patented design solutions for precise temperature control of OCXO, Dapu fundamentally solves the issue of high-power consumption in ordinary OCXOs, while shortening the warm-up time to less than 60 seconds.

The frequency stability and low phase noise characteristics of the ultra-low power OCXO can greatly improve the performance of the device (reduce communication latency, improve synchronization accuracy and system stability). At the same time, its low power consumption and fast start-up minimize the power consumption of the device and prolong its battery life, meeting the needs of application scenarios such as fast start-up and portable endurance.

As 5G application scenarios continue to expand and new, mobile communications have higher and higher expectations for OCXO’s low power consumption and miniaturization. Dapu will launch more new products in the direction of lower phase noise, lower power consumption, smaller package and higher stability to better serve customers and create more value!
