National Instruments PXI-6683 PXI Synchronization Module
The NI PXI-6683 (Part Numbers: 782109-01 and 782110-01) is a Timing and Synchronization Module that synchronizes PXI and PXI Express frameworks by utilizing GPS, IEEE 1588, and IRIG B to perform synchronous events. The PXI-6683 can create events and time signals at indicated synchronized future circumstances and timestamp input events with the synchronized framework time. The PXI-6683 highlights an onboard available temperature-compensated crystal oscillator (TCXO) that can be disciplined to GPS, IEEE 1588, and IRIG B for long-term stability. The user can also utilize the PXI-6683 module to route clock signals and triggers with low skew inside a PXI chassis or between multiple chassis, providing a strategy to synchronize numerous gadgets in a PXI framework.
The NI PXI-6683 gives one standard RJ-45 association for Ethernet communication. This port auto negotiates to the best possible speed—10 Mbps, 100 Mbps, or 1000 Mbps (auto-negotiation can be disabled by software). The Ethernet port is auto-MDI proficient, which implies crossover cabling is not fundamental while connecting the NI PXI-6683 to another system card. The NI PXI-6683 senses whether a crossed connection is required and performs the activity internally. The Ethernet port additionally considers full duplex activity, so traffic can be sent and received at the same time.
There are up to 13 PXI star triggers for each chassis. Each trigger line is a committed association between the framework timing slot and one other slot. The PXI Specification, Revision 2.1, requires that the propagation delay along each star trigger line be matched to within 1 ns. A typical upper limit for the skew in most NI PXI chassis is 500 ps. The NI PXI-6683 can course low skew triggers to the PXI_Star lines from any PFI line.

National Instruments PXI-6683 Frequently Asked Questions
Question: How many front panel connectors are on the PXI-6683?
Answer: There are six SMB male, 50 Ohm connectors and one standard RJ-45 Ethernet connector on the front panel of the PXI-6683.
Question: What type of protocols are supported by the NI PXI-6683?
Answer: The NI PXI-6683 supports the following protocols: GPS, IEEE-1588, IRIG-B, and PPS.
Question: What is the difference between the two part numbers for the PXI-6683?
Answer: For the two part numbers corresponding to the PXI-6683, the 782109-01 has a backplane clock override, a PXI Timing bus connector, a clock import, and PXI_STAR and PXI_TRIG Trigger Access. However, the 782110-01 does not have a backplane clock override, has PXI Hybrid and PXI Timing bus connectors, does not have a clock import, and only has PXI_TRIG Trigger Access.
Question: How long is the recommended calibration interval for the NI PXI-6683?
Answer: The NI PXI-6683 has a recommended calibration interval of 1 year.
