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 provides high-precision time aware systems (AVB/TSN) for an industrial environment, that requires a satellite synchronized IEEE 802.1 AS PTP Grandmaster and/or has widespread TSN networks that are connected through aa standard, non time sensitive network . 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 a grandmaster for 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 the satellite synchronized TSN (sub) systems mentioned above, ensuring reliable and precise time distribution across complex networked systems.
