Description
The National Instruments PXIe-6674T PXI Synchronization Module is a versatile device designed to generate and route synchronization signals such as clocks and triggers between devices within a PXI Express chassis, and it also interfaces with other PXI and PXI Express chassis or external instrumentation. With part numbers 781037-01, 199223G-01L, and 199225D-01, this module is integral for system synchronization.
The module supports low-voltage differential signaling (LVDS) trigger lines including PXIe-DStarA, PXIe-DStarB, and PXIe-DStarC, and it fully supports the PXI trigger lines to ensure seamless integration with PXI systems. The internal reference clock is a 10 MHz precision compensated crystal oscillator (OCXO), providing a stable time base for synchronized operations.
Users can take advantage of an adjustable clock frequency that can reach up to 1 GHz through Direct Digital Synthesis (DDS), allowing for flexibility in a variety of applications. The module’s functionality is fully configurable via NI-Sync software, which simplifies the process of setting up the synchronization parameters according to specific user requirements.
For ease of monitoring, the module is equipped with two LED indicators that provide real-time status information about the module’s operation. Furthermore, the NI-Sync software not only allows for detailed software control but also enables users to specify the exact frequency they require from the clock generation hardware, ensuring precision in synchronization tasks.
While the maximum requested clock frequency is 1 GHz, the module is designed to potentially exceed this range, although frequencies beyond 1 GHz are not officially specified, indicating additional flexibility for advanced users.
