TSN Systems Timepiece  

Precise time synchronization across Ethernet networks acting as a PTP Grandmaster

The TSN Systems Time Piece is a sophisticated yet compact device designed to receive Global Navigation Satellite System (GNSS) signals and accurately convert their timing information to the IEEE 802.1AS-2011 standard for precise time synchronization across Ethernet networks acting as a PTP Grandmaster.

This device is crucial for applications high-precision time aware systems (AVB/TSN), such as automotive, industrial automation, broadcasting, and other time-sensitive operations that require a satellite synchronized IEEE 802.1 AS PTP Grandmaster. A variety of hardware interfaces for Ethernet, USB, clocking and status LEDs complete the feature set.

The TSN Systems Time Piece is an essential tool for any organization requiring precise time synchronization over Ethernet networks. Its robust design, high accuracy, and comprehensive feature set make it ideal for a wide range of applications, including satellite synchronized TSN (sub) systems, ensuring reliable and precise time distribution across complex networked systems.
