National Instruments 785977-01 8-Channel PXI High-Speed Serial Instrument

The National Instruments 785977-01 (PXIe-6593) is a high performance 8-channel PXI high speed serial instrument tailored for engineers who require robust validation, interfacing and testing capabilities for various serial protocols. It leverages the powerful Xilinx Kintex Ultrascale FPGA that is available in configuration (KU060) which offers extensive reconfigurability to accommodate diverse application needs. The FPGA's multigigabit transceivers enable high speed data transmission and reception through up to eight TX and RX lanes.

This serial instrument is programmable using LabVIEW FPGA that provides users with a high degree of customization for specific application requirements. The onboard DRAM with a total of 4 GB across two banks ensures fast and efficient data processing. The DRAM boasts a maximum theoretical data rate of 17 GB/s. This feature is essential for applications that demand rapid data transfers and real time processing. The physical bus width of 32 bits and the clock rate of 1064 MHz underscore the system's capability to handle high speed operations seamlessly.

The 785977-01 also includes versatile digital I/O features with eight single ended channels supporting various voltage families such as 3.3 V, 2.5 V, 1.8 V, 1.5 V and 1.2 V. The high-speed serial MGT (Multi-Gigabit Transceiver) interface supports data rates ranging from 500 Mb/s to 16.375 Gb/s. The instrument is equipped with QSFP ports and compliant with SFF-8436 standards to accommodate both electrical and optical high-speed cables. The NI 785977-01 includes a robust MGT reference clock generator that supports a wide range of frequencies from 60 MHz to 1000 MHz with both AC-coupled and DC-coupled input/output options.

This ensures precise timing and synchronization in high speed data acquisition and processing tasks. The instrument's PCI Express Gen-3 x8 interface ensures rapid communication with the host system and supports demanding data throughput requirements. The module is compact yet powerful and fits seamlessly into PXI Express systems. The model comes with dimensions of 2.0 cm × 13.0 cm × 21.6 cm and a weight of 520 g. It operates efficiently within an ambient temperature range of 0 °C to 55 °C and is designed for reliable performance in demanding environments.
