Kintex 7 FPGA, Digital Reconfigurable I/O Device—The PCIe‑7821 is a reconfigurable I/O (RIO) device that features a user-programmable FPGA for onboard processing and flexible I/O operation. With LabVIEW FPGA, you can individually configure the digital lines as inputs, outputs, counter/timers, PWM, encoder inputs, or specialized communication protocols. You can also program custom onboard decision making that executes with hardware-timed speed and reliability. Each line offers software-selectable logic levels. The PCIe‑7821 is well-suited for a wide variety of applications, such as high-speed waveform generation, sensor simulation, hardware‑in-‑the‑loop (HIL) test, bit error rate test, and other applications that require precise timing and control.
