PTP grandmaster clocks

The ideal sync solution

Whether at the edge or core of the mobile backhaul network, deep in radio access networks, in financial trading, utility distribution or defense communication networks, our portfolio of precise timing devices provides the ideal solution. Complemented by our powerful synchronization network management system, configuration, management, monitoring and assurance of your entire synchronization infrastructure becomes simple. What’s more, our miniature network timing solutions enable precise synchronization in the most space-restrictive environments, indoor and outdoor, and even in deep urban canyons with no clear sky view.


Flexibility and choice

With our series of PTP grandmaster clocks, we’re answering the key challenges facing today's operators as they roll out next-gen technologies such as LTE-A and 5G, and addressing the urgent need for synchronization across all industries. Oscilloquartz timing devices are engineered for excellent performance even in the most extreme conditions. Our pioneering product range delivers the best holdover performance on the market despite the most compact footprint. Our PTP grandmasters consist of a GNSS-receiver and a PTP engine delivering PTP service over Ethernet ports. For flexibility and freedom, they are designed to operate with PTP slaves from any vendor.


Time to meet our grandmaster clocks

On the high end, our OSA 5430 is a modular, high-performance IEEE 1588v2 PTP core grandmaster that provides ultimate scale with a carrier-class design and highest availability. When looking for compactness, our OSA 5401, a miniature SFP-based PTP grandmaster, boundary and slave clock, is designed for deployment deep in the radio access network, enabling you to upgrade legacy systems with IEEE 1588v2 PTP and synchronous Ethernet functionality. Our OSA 5405, 5410, 5420 and 5430 series are PTP grandmasters for deployment at the network edge close to the application. We also offer a revolutionary dual GNSS antenna to deliver accurate synchronization without the need for satellite visibility.
