Overview

Product overview

Key product information and technical features.

The PCIe-7820 brings FPGA-based digital I/O to a computer-based PCI Express system. Its user-programmable FPGA supports onboard processing and hardware-timed operation rather than relying solely on host software for digital control.

With LabVIEW FPGA, the digital lines can be configured for inputs, outputs, counter/timers, PWM, encoder inputs, or specialized communication protocols. The device uses VHDCI front connections and single-ended signaling with selectable digital logic levels.

  • User-programmable Kintex-7 160T FPGA for reconfigurable digital operation.
  • 128 bidirectional digital channels and four external clock inputs.
  • Maximum clock, acquisition, and generation rates of 80 MHz.
  • Selectable digital logic levels of 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
  • Supports custom onboard decision-making with hardware-timed operation.
  • Specified operating temperature range of 0 °C to 55 °C.
