Open Timecard Mini - Precision Timing
The Open Timecard Mini Precision Timing is a compact, GNSS-disciplined PTP and NTP grandmaster clock from the Open Timecard Mini family — precision time for servers, edge systems and labs without a rack appliance.
Key features
- NTP, PTP, PPS & frequency distribution direct from the device
- Multi-band GPS/GNSS receiver
- Integrated oscillator for holdover when GNSS is unavailable
- Full PTP profile support
- Compact form factor for edge, embedded and lab deployments
PTP profile support
- Default & Enterprise profiles (E2E and P2P)
- IEC 61850-9-3 Utility profile
- IEEE C37.238-2017 (and 2011) Power profile
- ITU-T G.8265.1(/2) & G.8275.1(/2) Telecom profiles
- SMPTE 2059-2 & AES67/RAVENNA broadcast profiles
Applications
Deployed in finance (in-server time sync for trading systems and MiFID II style compliance), broadcast (studio and live event genlock), telecom/5G (space-efficient PRTC at the edge) and defence (robust timing in vehicle and mobile units).
