The National Instruments 785977-01, also known as the PXIe-6593, is a high-performance 8-channel PXI high-speed serial instrument designed for engineers seeking advanced validation, interfacing, and testing capabilities across various serial protocols. This instrument is powered by the Xilinx Kintex UltraScale FPGA (KU060), which provides significant reconfigurability to meet diverse application needs. Equipped with multigigabit transceivers, the PXIe-6593 facilitates high-speed data transmission and reception through eight transmit and receive lanes.

The PXIe-6593 is programmable via LabVIEW FPGA, offering extensive customization options for specific application requirements. It features an onboard dynamic RAM (DRAM) configuration of 4 GB distributed across two banks, providing a maximum theoretical data rate of 17 GB/s, essential for applications requiring rapid data transfer and real-time processing. With a physical bus width of 32 bits and a clock rate of 1064 MHz, this instrument seamlessly supports high-speed operations.

In addition to its robust serial capabilities, the 785977-01 offers versatile digital I/O features with eight single-ended channels that accommodate various voltage families, including 3.3 V, 2.5 V, 1.8 V, 1.5 V, and 1.2 V. The high-speed serial Multi-Gigabit Transceiver (MGT) interface supports data rates from 500 Mb/s to 16.375 Gb/s, and the instrument includes QSFP ports compliant with SFF-8436 standards, ensuring compatibility with both electrical and optical high-speed cables.

Designed with precision in mind, the PXIe-6593 incorporates a robust MGT reference clock generator that supports a wide frequency range of 60 MHz to 1000 MHz with both AC-coupled and DC-coupled input/output options, enabling accurate timing and synchronization for high-speed data acquisition and processing. The PCI Express Gen-3 x8 interface allows for rapid communication with host systems, fulfilling demanding data throughput requirements. Compact yet powerful, the module measures 2.0 cm × 13.0 cm × 21.6 cm and weighs 520 g, operating efficiently within an ambient temperature range of 0 °C to 55 °C, ensuring reliable performance in challenging environments.
