Description
The National Instruments PXI-7813 PXI Digital Reconfigurable I/O Module (Part number: 779362-01) is designed to offer a robust solution with 160 TTL compatible, bidirectional digital I/O channels. These channels operate at I/O logic levels of 3.3 volts and 5 volts, with an output current of 04 mA, and are safeguarded with input overvoltage protection ranging from -0.5 volts to 7 volts.
At the core of the module is a powerful FPGA, specifically a Virtex-II V3000 with 28,672 Flip-Flops, which allows for extensive reconfigurability and is paired with a maximum onboard clock frequency of 40 MHz. The device interfaces with systems via a standard PXI bus connector and offers three DMA channels for efficient data transfer.
Connectivity is facilitated through four 68-pin VHDCI female connectors, ensuring versatile connection options. The PXI-7813 is ideal for applications requiring high-speed signal generation, custom communication protocols, sensor simulation, precise timing and control, as well as HIL testing and bit error rate testing. Despite its obsolete status, as announced by National Instruments, it remains available for purchase and repairs through Apex Waves.
