The NI PCI-1588 is a PCI-based synchronization device that implements IEEE 1588-2008 Precision Time Protocol (PTP) for precise clock and event synchronization across networked systems and instruments. Operating as either an IEEE 1588 master or slave clock, the card achieves sub-microsecond synchronization accuracy through an onboard FPGA that automatically adjusts phase and frequency of the internal clock. The device synchronizes with IEEE 1588-compatible instruments and computers via integrated Ethernet, while non-1588 devices connect through three front-panel PFI lines or SMB connectors on the PCI bracket. Additional synchronization with other PCI instruments in the same host machine occurs via the RTSI bus.
The card generates programmable clock signals and events at specified future times and timestamps input events with system time. Output frequencies range from DC to 1 MHz with a minimum pulse width of 36 ns and 50 Ω nominal impedance. The integrated Ethernet port auto-negotiates 10 or 100 Mbps speeds using an AMD PCNET Family PCI Ethernet Adaptor and connects via RJ-45 connector.
