OCP-TAP Timecard

The OCP-TAP Timecard is the reference implementation of the Open Compute Project Time Appliance Project — 100% open source from FPGA gateware to PCB layout, validated by Meta, Microsoft and the OCP community. It turns any x86_64 server into a PTP grandmaster and NTP stratum-1 source.

Key features

FPGA gateware, schematics, layout, firmware and driver all published under permissive open-source licences — fully auditable
PCIe x4 interface
Modular oscillator: OCXO, Rubidium Black or Rubidium Black+ without changing the base card
Industrial temperature range: -40°C to +85°C
Hyperscale-validated: the timing card design Meta runs across its global fleet

Oscillator variants

Variant	Oscillator	Holdover (24 h)
OCXO	Rakon, 0.5 ppb stability	<1.5 µs
Rubidium Black	Microchip MAC SA-53	<300 ns
Rubidium Black+	Microchip MAC-SA55	<200 ns

Applications

Hyperscale fleet timing (one card per rack distributing PTP across the fabric), telecom PRTC in G.8275.1 chains, and defence/government programmes that require a fully auditable, vendor-independent timing stack.

Complete the setup

Pair it with our multi-band GNSS antenna (L1/L5) for GNSS reception, browse OCP-TAP accessories and services, or compare the full range of PTP & NTP grandmaster clocks.
