PXIe, x8 Gen 3 KU035 FPGA, 2 GB DRAM PXI FPGA Module for FlexRIO—The PXIe-7991 provides a LabVIEW-programmable Xilinx Kintex UltraScale KU035 FPGA with a mezzanine connector interface for hosting custom I/O developed using the Module Development Kit for FlexRIO. The mezzanine connector interface features 70 low-voltage differential signaling (LVDS) pairs for data movement in addition to single-ended single-ended general-purpose input/output (GPIO) for configuration, clocking, and triggering. Additionally, the PXIe-7991 features an auxiliary I/O connector with eight single-ended GPIO for digital communication and triggering, as well as for Xilinx GTH Transceivers for data streaming at up to 16 Gbps for each lane.
