The following chapter contains information about the PXIe-7902 clocking architecture.

The PXIe-7902 is a high-speed serial interfacing module. The PXIe-7902 hardware architecture allows you to fully customize your serial digital protocol application. The high-speed serial interface uses Xilinx GTX transceiver technology; you can reuse existing protocol IP that works with Xilinx GTX transceivers, or you can develop your own protocol IP. If you develop your own protocol IP, the IP must be developed for a Xilinx Virtex-7 GTX transceiver.

Note The PXIe-7902 hardware does not require calibration. PXIe-7902-based projects consist of the following key components:
  • PXIe-7902 front panel connectors for data, clocking, and triggering external to the module
  • Socketed CLIP for HDL IP and interface definition from the FPGA VI to the PXIe-7902 front panel
  • Xilinx Virtex-7 FPGA
  • Dynamic random access memory (DRAM)
  • NI-defined bus interface from the FPGA to the host PC

    The following figure illustrates the key components of the PXIe-7902 architecture.
