Why Open Timecard?


  • A Standalone Grandmaster

    The Open Time Card module can function as a closed system or be integrated with a host system when coupled with any network adapter.

  • Add resilience to critical infrastructure

    The Open Time Card has over 5 different oscillator options ranging from stable Quartz through to industry leading rubidium for outstanding holdover.

  • High Accuracy Time Distribution

    Open Time Card has SyncE and PTP built-in for precise timing signal distribution, simplifying network topologies and timing deployments without complex systems.

  • Flexibility

    The Open Time Card is designed with various industries in mind, from finance to broadcast, government, and defense to telecom.
