National Instruments PXIe-7966R PXI FPGA Module for FlexRIO
Designed to support peer-to-peer (P2P) streaming, the PXIe-7966R (Part Number: 781805-01) is a PXIe FPGA module featuring a Xilinx Virtex-5 SX95T FPGA. This module utilizes NI’s P2P technology, which enables direct point-to-point data transfer between multiple instruments without adding stress to the host memory or processor​
The Virtex-5 SX95T FPGA in the NI PXIe-7966R is reconfigurable and provides 58,880 Look-Up Tables (LUTs), 640 DSP48 Slices, and 8,784 kbits of embedded BRAM (block RAM). This module includes two independent DRAM banks, each with 256 MB of memory, providing a total of 512 MB DRAM. It supports a maximum theoretical data transmission rate of 1.6 GB/s per bank​
The PXIe-7966R supports multiple clock sources, including the 100 MHz PXIe timebase, as well as a default 40 MHz onboard clock. This module supports three data transfer modes: Direct Memory Access (DMA), programmed I/O, and interrupts. It is compatible with x4 PXI Express and PXI Express Hybrid slots
The PXIe-7966R is considered Obsolete and is no longer available from National Instruments, but the PXI FPGA Module will still be available for purchase and repairs in perpetuity with Apex Waves.
