PXI-XJLink2

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.

  • Modular, scalable solution.
  • Self-contained licence allows you to run XJTAG from a standalone PXI rack.
  • Re-configurable unit for multiple UUTs saving costs.
  • Easy integration with NI’s LabVIEW*.

PXI-XJLink2 JTAG Controller

Features

  • 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, <100mA).

  • 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.
  • Simple DLL API interface: includes commands such as tmsReset() irScan() drScan() etc.
  • Full tutorials provided for all software packages based on supplied demonstration hardware.

PXI/cPCI solution

PXI-XJLink2 provides a JTAG solution that can be integrated with other test equipment using the industrial PXI standard designed to minimise the effect of electrical noise. CompactPCI® compatible so it can be used in any cPCI or PXI-based test system.

Configurable JTAG interface

Only one simple cable assembly is required to connect to your target board — no extra adapters needed. The 20-way connector is configurable to match the connector pinout on the PCB. The ability to change the pinmap for the JTAG signals simplifies the process of connecting your XJTAG test system to the Unit Under Test.

Integration

The standard .NET and COM interfaces allow you to integrate XJTAG testing with test executives such as NI LabVIEWTM, LabWindowsTM/CVI, with ATE machines, or a bespoke application written in languages such as Visual Basic .NET® or C#®. XJTAG provides coding examples for LabVIEW, LabWindows, C#, C++ and Visual Basic.

Flexible & scalable

From a single port system for development to multiport test and programming systems in production, the PXI-XJLink2 module provides a flexible, scalable JTAG solution.

With self-contained licences, all XJTAG hardware provides flexibility as no network connection is required for the test system to run.

Advanced connectivity

PXI-XJLink2 has variable signal termination, so it can handle boards both with and without signal termination. The advanced auto-skew control enables you to get the maximum frequency out of your JTAG chain and cable.
