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 - Structural Overview

 

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. The drivers have to be installed on your PC or server. The syn1588® PTP Stack has to be invoked on your system as well to complete the IEEE1588 node.

The syn1588® PCIe NIC comes with a binary run-time license of the syn1588® PTP Stack.
