Open Timecard Mini - Precision Timing module is a compact PTP grandmaster clock with 5ns UTC accuracy, 1.5us/8hrs holdover, and multi-band GNSS. Supporting IEEE 1588 (PTP), NTP, and SyncE protocol, it ensures precise frequency sync and reliable timing.
Why Precision Timing Module?
-
<5ns Timing Accuracy
Delivers <5ns precision using u-blox LEA-F9T GNSS and ±1 ppb stability from oscillator, ensuring exact timing for 5G networks, financial trading, and scientific instruments.
-
1.5μs/8Hrs Holdover Stability Without GNSS
If GNSS signal is lost, the OCXO maintains 1.5 microseconds of drift over 8 hours, matching telecom standards for backup timing in data centers and power grids.
-
Support multi-satellite systems
The 184-channel u-blox F9 engine locks onto multiple satellite systems (L1/L2/L5 bands), with 26-second cold starts and 1-second reacquisition, ensuring reliability in remote or obstructed areas.
-
Adjustable Frequency
On boarded clock generator allows sub-picosecond tuning, while the OCXO supports 1 ppt adjustments, critical for quantum computing, radar, and lab equipment requiring exact frequency control.
