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 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.
The syn1588® PCIe NIC had been re-designed to board Revision 2.3 observing the full compatibility on function level. The re-design was required to deal with the excessive lead times of electronic components we are faced with in the whole industry. We took the chance to update the clocking infrastructure on the board to achieve an even better accuracy and stability.

Timestamping of User Defined Packets
The timestamping unit of the syn1588® Clock_M IP Core used in the syn1588® PCIe NIC allows detecting two independent classes of Ethernet packets in both receive and transmit direction respectively. One packet class in each direction is used for detecting PTP packets and thus used by the syn1588® PTP Stack. The second timestamping unit may be used by the application software to detect an arbitrary class of Ethernet packets in each direction and draw a timestamp upon transmission or reception of a packet meets the user defined filter condition.
This application note briefly outlines the required actions in the user software.
