What it is
The Open TimeCard Mini V3 packs a full multi-band GNSS receiver, an integrated OCXO and a complete PTP / NTP / PPS stack onto a single low-profile PCIe card. It's the drop-in choice when you need accurate time inside an existing server without adding a rack unit — and it ships with every major PTP profile supported out of the box.
Protocol support
No profile add-ons, no licence keys — every supported profile ships pre-configured.

Capabilities
Default (E2E and P2P), Enterprise-Draft, IEC 61850-9-3 Utility, IEEE C37.238 Power, ITU-T G.8265.1/2 and G.8275.1/2 Telecom, SMPTE 2059-2 and AES67/RAVENNA — all supported on the same port.
< 30 ns absolute timing accuracy. Configurable L1+L2 or L1+L5 dual-band tracking of GPS, Galileo, GLONASS and BeiDou with -167 dBm tracking sensitivity.
0.1 ppb short-term stability. 1.5 µs holdover over 8 hours once compensated.
Rated for ±5 ppb stability under shock and vibration — built for broadcast trucks, mobile command vehicles and industrial environments.
Ships as full-height or half-height PCIe — fits from desktop workstations to space-constrained 1U chassis without compromise.
Built-in 1 GbE network port serves the full protocol stack — no additional hardware, no external oscillator, no second card.
Ships with the TimeBeat software stack pre-configured. The jitter attenuation engine filters network noise, asymmetric delay and oscillator phase noise from every timestamp — delivering a clean, stable clock signal with sub-nanosecond residual phase noise to your downstream applications.

What a PTP grandmaster clock actually does, how to choose one, and what separates a grandmaster you can trust from one that quietly drifts. Written by TimeBeat's engineering team for network architects deploying IEEE 1588 in production.
Secure, resilient timing for mission-critical communications, radar, UAVs and C4ISR.
Nanosecond-accurate synchronisation for grid stability, substation automation and renewable integration.
Process safety, incident response and cybersecurity through precision timing.
For most of computing, millisecond-class clock synchronisation is fine. For a growing list of use cases — finance, broadcast, 5G, AI, distributed databases — it isn't. A field guide to recognising when your application has crossed the line and millisecond-grade time has become a liability.
Meta's published engineering blog has documented one of the most ambitious PTP deployments in the industry — replacing NTP across the entire fleet with hardware-timestamped IEEE 1588. What they built, why they built it, and what it tells the rest of the industry about where hyperscale timing is heading.
