Chapter 5 Counter Signal Routing and Clock Generation
PXIe-DSTAR<A..C>
PXI Express devices can provide high-quality and high-frequency point-to-point connections
between each slot and a system timing slot. These connections come in the form of three
low-voltage differential star triggers that create point-to-point, high-frequency connections
between a PXI Express system timing module and a peripheral device. Using multiple
connections enable you to create more applications because of the increased routing capabilities.
Table 5-5 describes the three differential star (DSTAR) lines and how they are used.
For more information, refer to the PXI Express Specification at
www.pxisa.org.
Table 5-5. PXIe-DSTAR Line Descriptions
Trigger Line Purpose
PXIe-DSTARA Distributes high-speed, high-quality clock signals from the
system timing slot to the peripherals (input).
PXIe-DSTARB Distributes high-speed, high-quality trigger signals from the
system timing slot to the peripherals (input).
PXIe-DSTARC Sends high-speed, high-quality trigger or clock signals from the
peripherals to the system timing slot (output).
