National Instruments introduces PCI Express/PXI Express high-speed digital I/O instruments. Based on a new architecture that reduces cost and maximizes throughput, the new NI 6535/36/7 digital I/O devices offer engineers a low-cost, high-throughput digital interface for a wide range of applications including interfacing to image sensors and display panels, emulating communications protocols, and testing ADCs/DACs. These products include the following features:

  • Continuous data streaming up to 200 MB/s of dedicated throughput over a x1 PCI Express interface
  • Maximum clock rates up to 50 MHz from internal or external sources
  • Selectable voltage levels of 2.5 and 3.3 V (5 V compatible) per direction
  • Per-channel directional control of 32 digital I/O lines
  • Multiple handshaking modes with synchronous and asynchronous timing
  • Compatibility with existing NI 6533 and NI 6534 NI-DAQmx applications
