Oregano Systems syn1588® PCIe NIC is a PCI Express Gbit network interface card with IEEE1588 hardware support. A PC equipped with the syn1588® PCIe NIC receives highly accurate time (<10 ns) independent from network utilization and CPU load without real-time requirements for the node’s operating system.
The syn1588® PCIe NIC acts basically as a standard 10/100/1000 MBit/s Network Interface Card (NIC). Besides the standard function of sending and receiving Ethernet packets, the syn1588® PCIe NIC includes dedicated hardware to implement high accuracy clock synchronization following the IEEE1588 standard.
The syn1588® PCIe NIC includes a full-featured IEEE1588 hardware clock as well as complex timestamping hardware. All time critical elements of an IEEE1588 system are embedded in the syn1588® PCIe NIC thus removing all timing constraints from the software. There are no real-time requirements for the operating system or the software stack. Due to its special structure, the CPU load for the required IEEE1588 stack (e.g. Oregano Systems syn1588® PTP Stack) is negligible.

syn1588® PCIe NIC – Technical Features
The syn1588® PCIe NIC allows to easily create a standard-compliant IEEE1588 node. For this both
- hardware (the syn1588® PCIe NIC)
- and software (the syn1588® PTP Stack with drivers)
are required. The syn1588® PCIe NIC is plugged into your PC or server. Now, the drivers have to be installed. Finally, the syn1588® PTP Stack has to be invoked on your system to complete the IEEE1588 node. Note, the syn1588® PCIe NIC comes with a binary run-time license of the syn1588® PTP Stack.

syn1588® PCIe NIC – Applications
Distribute accurate time to IEEE1588 slaves
PCs equipped with the syn1588® PCIe NIC synchronize their local hardware clock with an accuracy of 10 ns or better to the absolute time information distributed by an IEEE1588 grandmaster.
syn1588® PCIe NIC acting as PTP Slave
Implement an IEEE1588 grandmaster
A PC equipped with the syn1588® PCIe NIC may act as an IEEE1588 Grandmaster on your network. The syn1588® PCIe NIC may synchronize its local hardware clock to an external absolute time reference like e.g. a GPS receiver.
syn1588® PCIe NIC acting as PTP Master
Oregano Systems provides a utility the – syn1588® PTP Management Software – free of charge that allows users to remotely manage all IEEE1588-2008 nodes in a network.
Please check the Application Note "Ordering syn1588® PCIe NICs" describing the available options for the syn1588® PCIe NIC and their respective ordering number.
Please note that we generally recommend a high quality OCXO oscillator for all IEEE1588 master applications.
