Page 7: System Reference Clock
System Reference Clock The NI PXIe-1082 chassis supplies PXI_CLK10, PXIe_CLK100, and PXIe_SYNC100 to every peripheral slot with an independent driver for each signal. An independent buffer (having a source impedance matched to the backplane and a skew of less than 500 ps between slots) drives PXI_CLK10 to each peripheral slot. - Page 8 If the 10 MHz clock is present on both the PXI_CLK10_IN pin of the System Timing Slot and connector J36, the signal on the System Timing Slot is selected. Refer to Table 1, which explains how the backplane selects the 10 MHz clocks. 8-Slot NI PXIe-1082 Backplane Installation Guide ni.com...

PXIe_SYNC100 signal. On the next PXI_CLK10 edge, the PXIe_SYNC100 signal restarts. This allows several chassis to have their PXIe_SYNC100 in phase with each other. Refer to Figure 7 for timing details with this method. © National Instruments 8-Slot NI PXIe-1082 Backplane Installation Guide... -
