National Instruments PXI-7951R PXI FPGA Module for FlexRIO
Designed for FlexRIO-based data acquisition systems, the NI PXI-7951R (Part Number: 780560-01) is a reconfigurable PXI module with an integrated LX30 FPGA. The reconfigurable FPGA utilized in the construction of this module is from the Virtex-5 family of FPGAs. This PXI FPGA module for FlexRIO supports 3 DMA channels for high-speed data transfer between the FPGA and the host system. The 66 GPIO (general-purpose I/O) paired channels of this module can be configured through software to operate as 132 independent, single-ended channels. Up to 400 Mb/s (megabits per second) single-ended (SE) configuration rates are possible with this module.
The NI PXI-7951R supports LabVIEW FPGA features such as Single-Cycle Timed Loops (SCTLs), FPGA clocks, and hardware-timed processing. The FPGA incorporated in this module can be accessed and configured with the help of the NI LabVIEW FPGA Module and has 1,152 kbits of embedded block RAM. The PXI-7951R can also be coupled with the NI-6581 Adapter Module to fulfill the requirements of 100 MHz digital I/O.
The PXI-7951R FPGA module is no longer available from National Instruments, but it will remain available in perpetuity with Apex Waves for both purchase and repair services.
