National Instruments PXI-7951

The National Instruments PXI-7951 PXI FPGA Module for FlexRIO (Part Number: 780560-01) is designed to provide versatile and customizable I/O solutions for LabVIEW FPGA applications. Featuring a Xilinx Virtex-5 LX30 FPGA, this module offers an impressive 132 I/O lines from a single terminal, which can be configured as 66 differential pairs, enabling flexible system design and implementation. The PXI-7951 can be integrated with various FlexRIO connector modules that facilitate high-performance and automated I/O capabilities, creating a fully reconfigurable instrument programmable via LabVIEW FPGA software. With up to 512 MB of on-board DRAM, this module supports data transfer rates of up to 3.2 GB/s, leveraging high-speed processing capabilities supported by 640 dedicated DSP slices for efficient single-cycle multiplication and filtering tasks. The PXI-7951 is equipped with the STC-3 application-specific integrated circuit (ASIC) to ensure improved, high-bandwidth PCI Express x4 communication with the PXI Express chassis backplane. This ASIC enhances the performance of host communications while enabling advanced point-to-point data transfer technology, allowing seamless data exchange between the PXI Express NI FlexRIO modules at speeds exceeding 800 MB/s with minimal latency. Additionally, the specialized data switches embedded within the PXI Express chassis facilitate direct communication between modules, bypassing the host controller for increased efficiency. Although the PXI-7951 has reached mature status, it remains available for purchase and repair through Apex Waves.

The module dimensions are 7.4 x 5.1 inches and weighs 6.7 ounces, and it comes with a standard warranty of 2-3 years. User and maintenance manuals for the PXI-7951 are available for downloading, and potential customers are encouraged to contact a sales representative for pricing information.
