Page 7: System Reference Clock
System Reference Clock The NI PXIe-1075 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 1 ns between slots) drives PXI_CLK10 to each peripheral slot. - Page 8 PXIe_CLK100 and PXIe_SYNC100 No clock present No clock present Backplane generates its own clocks No clock present 10 MHz clock present PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 all phase-locked to Rear Chassis Panel—10 MHz REF IN 18-Slot NI PXIe-1075 Backplane Installation Guide ni.com...
