The National Instruments PXIe-6674 / PXIe-6674T Timing and Multichassis Synchronization Module offers the most advanced timing and synchronization capabilities for PXI Express systems. The module generates and routes clocks and triggers between devices in a PXI Express chassis. In addition, it can route these signals to other PXI and PXI Express chassis as well as third-party instrumentation. The NI PXIe-6674T unlocks the advanced low-voltage differential signaling (LVDS) trigger buses, PXIe-DStarA, B, and C, on PXI Express while fully supporting the PXI trigger bus, PXI_TRIG. This module can generate two types of clock signals: a highly stable 10 MHz clock based on an onboard precision OCXO reference, and a second clock up to 1 GHz from the direct digital synthesis (DDS) clock generation circuit.
