National Instruments PCI-1588 Synchronization Device

The National Instruments PCI-1588 (Part Number: 779497-01) is an IEEE 1588-compatible Synchronization Device. This device employs the IEEE 1588-2002 protocol to achieve synchronization between events and clocks with other IEEE 1588-compatible computers or instruments​. The NI PCI-1588 can operate as either an IEEE 1588 slave or master clock. An onboard FPGA incorporated in this device adjusts the phase and frequency of a built-in IEEE 1588 clock automatically. The device has an output frequency of DC to 1 MHz, a minimum pulse width of 36 ns, and requires 1 PCI slot for operation​.

This interface gets its clock synchronized with other IEEE 1588-based devices using an integrated Ethernet port. With this synchronized timebase and the use of PFI (Programmable Function Interface) lines, the IEEE 1588 PCI card can synchronize events with other non-1588 instruments, such as PLCs or traditional instruments via SMB connectors provided on the PCI bracket. For synchronizing this device with other PCI instruments installed in the same host machine, users can utilize the RTSI bus as well. The front panel of the NI PCI-1588 includes an RJ-45 Ethernet connector, three PFI connectors (PFI0, PFI1, and PFI2), one link LED, and one speed LED. The Link LED and Speed LED indicate Ethernet link condition and speed, respectively​. In addition to synchronization over Ethernet and generation of clock and event signals, the PCI-1588 can also be used for timestamping incoming signals.

The PFI terminals on this synchronization device can operate as timestamped inputs or future clock signal outputs. With this module, users can achieve sub-microsecond synchronization. The Ethernet port auto-negotiates to the best possible speed—10 or 100 Mbps​. The NI device is operated using the NI-Sync driver software, which is compatible with application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Visual C/C++. The NI PCI-1588 measures 6.87 x 4.19 in. in physical dimensions. It has a recommended operating temperature range of 0 to 55 °C, and a storage temperature range of –20 to 70 °C​

PCI-1588 has reached Mature Status, meaning it is no longer actively developed by National Instruments but is still available for purchase and repair from Apex Waves.
