Open Timecard - Quartzlock Rubidium
The Open Timecard with quartz OCXO or Rubidium oscillator: a modular PCIe PTP grandmaster clock card where the oscillator is chosen for your holdover requirement — from ±1.5 µs/24 h (OCXO) down to ~200 ns/24 h (Rubidium Black+).
Key features
- Full-height and half-height PCIe slot profiles, modular by design
- NTP, PTP, PPS, SyncE & frequency distribution direct from the card
- 1 GbE built-in network port; IEEE 1588 transparent-clock Ethernet switch with SFP
- 2× Intel i226 with PTM on card, multiple 1588 hardware timestamping registers
- Onboard Raspberry Pi CM4 running PTP & NTP
- u-blox LEA-F9T multi-band GNSS (2.5 ns to UTC), full constellation support
- Frequency output 1 Hz – 1 GHz, plus frequency input
- OCXO or Rubidium oscillator options; anti-jam & anti-spoof technology
- Linux operating system; up to 3 units per 1RU with the rack kit
Oscillator options
| Option | Holdover (24 h) | Notes |
|---|---|---|
| Rakon ROD2522S2 OCXO | ±1.5 µs | ±0.5 ppb over temperature, ±0.2 ppb daily aging |
| Rubidium Black (SA-53) | ~0.5 µs | ≤5×10-11 at 1 s, 120 mW typical |
| Rubidium Black+ (SA-55) | ~0.2 µs | ≤3×10-11 at 1 s, 2-minute warm-up |
Applications
Telecom/5G PRTC deployments, financial trading compliance, defence PNT resilient to GNSS threats, and broadcast timing — with clock-ensemble UTC verification for secure, resilient PNT.
Complete the setup
Pair it with our multi-band GNSS antenna (L1/L5) for GNSS reception, browse Open Timecard accessories, or compare the full range of PTP & NTP grandmaster clocks.
