XJTAG PXI module

XJTAG PXI module

32 bit PXI/c PCI bus interface, 3U form factor, complete with LabView VIs

The PXI XJLink2 module allows the integration of XJTAG into PXI-based test systems. PXI XJLink2 has one JTAG controller that can be connected to up to 4 JTAG chains, which are configurable for pinout and voltage. It is easily integrated with LabVIEWTM with a full set of Virtual Instruments (VIs) included.


  • 32 bit PXI/cPCI bus interface.
  • NI LabVIEW Virtual Instruments (VIs) available (National Instruments).
  • 3U form factor.
  • Connects to up to 4  JTAG chains on the  UUT.
  • Handles different cable and board configurations.
  • TCK clock frequencies up to 166 MHz.
  • Two different voltages can be configured, from 1.1V to 3.3V in 0.1V steps
  • Visual indication of test status.
  • Adjustable JTAG signal termination.
  • Automatic signal skew control.
  • Can supply power to the target board through the JTAG connector (3.3V,
  • Built in voltage meter on all I/O pins. Voltage input: Min 0, Max 5 V
  • Frequency counter on all I/O pins. Frequency input: Min 1 Hz, Max 200 MHz.   Selectable measurement period of 1 ms, 10 ms, 100 ms, 1 s, 10 s
  • JTAG signals are +5V tolerant.
  • Spare pins on the JTAG connector can be used to indicate the test status or  to control other items — e.g. hold a board in reset / turn on a PSU.
  • Pins can also be used as general purpose I/O during testing, for example for fast Flash programming.
