The National Instruments 781037-01 PXI Synchronization Module, part of the PXIe-6674T series, is designed to efficiently produce and route clocks and triggers among PXI Express chassis devices as well as third-party instrumentation. This module features advanced low-voltage differential signaling (LVDS) for PXIe DStarA, PXIe DStarB, and PXIe DStarC trigger signals, while ensuring compatibility with standard PXI trigger lines. Its robust architecture includes a precision oven-controlled crystal oscillator (OCXO) that generates a highly stable 10 MHz clock, along with a second clock derived from a direct digital synthesis (DDS) circuit. The operational frequency range is impressive, offering a minimum of 1 MHz and reaching up to 100 MHz for Clk10PLL, 200 MHz for FPGA, and an exceptional 1 GHz for PXIe-DStarA. The module maintains precise timing with a maximum delay of 14.8 ns across its specified temperature range, and typically achieves a ClkIn to PXI_Clk10_In delay of 6.75 ns at 25°C. The OCXO ensures remarkable accuracy, holding a nominal frequency of 10 MHz with an accuracy of ±80 ppb after one year of calibration within a temperature range of 0°C to 55°C, while delivering peak-to-peak temperature stability of less than 10 ppb and long-term stability rated at ±50 ppb/year. The 781037-01 facilitates rapid access to all other PXIe slots directly connected to the System Timing Slot via LVDS PXIe-DStarB signals, and it can also integrate with PXIe-DStarC signals from additional slots to support seamless sharing of clock and trigger signals among modules within the chassis.
