XJLink is a small, portable, USB hardware devices that provides a high speed interface (480Mbps) to the JTAG chain on a circuit board. XJLink-USB 2.0 to JTAG Interface

The small, lightweight design means the XJLink can easily be moved to the Unit Under Test (UUT). Advanced features, like their programmable JTAG signal pin position, switchable power supply and auto signal skew, make it easy to connect to a wide range of circuit boards. Simple to install and use due to the USB plug-and-play ability. XJLink-USB 2.0 to JTAG Interface

Key Benefits

  • Small, lightweight, portable design: ideal for lab and field work.
  • Self-contained licence allowing you to use the XJTAG system on multiple machines.
  • Re-configurable unit for multiple UUTs saving costs.
Features XJLink
Up to 4 TAP connections to UUT
Handles different cable and board configurations
USB bus-powered (no external PSU)
TCK clock frequencies up to 50MHz
Two different voltages can be configured, from 1.1V to 3.3V in 0.1V steps
Button to start test
Visual indication of test status
High speed USB 2.0 interface, backwards compatible with USB 1.0 & 1.1
Adjustable JTAG signal termination
Spare pins on the JTAG connector can be used in place of the button or to indicate the test status
Pins can also be used as general purpose I/O during testing, for example for fast Flash programming
Spare pins can be used to control other items — e.g. hold a board in reset / turn on a PSU
Automatic signal skew control
Can supply power to the target board through the JTAG connector (3.3V, <100mA)
Built in voltage meter on all I/O pins. Voltage input: Min 0, Max 5V
Frequency counter on all I/O pins. Frequency input: Min 1Hz, Max 200MHz. Selectable measurement period of 1ms, 10ms, 100ms, 1s, 10s
JTAG signals are +5V tolerant
Runs on 8 / 7 / XP / Vista
Simple DLL API interface: includes commands such as tmsReset() irScan() drScan() etc.
Available in two colours allowing users to differentiate between units with different licences

Your test system where you want it

The adapter contains the license for your XJTAG system. This allows you to easily move your licenses around on and off site to give you maximum flexibility. This also means you aren’t tied to one machine to do your XJTAG testing.

Configurable JTAG interface

Only a simple cable assembly is required to connect to your target board, no extra adapters are needed.

The 20-way connector on the XJLink is configurable from your test system. The ability to change the pinmap for the JTAG signals simplifies the process of connecting your XJTAG test system to the Unit Under Test. Can be configured to Xilinx Parallel ®, Altera ByteBlaster ®, ARM MultiICE ®, or any other pinout currently in use.

Light & portable

XJLink can work with a laptop PC with a USB port and can supply power to low-power target systems, so testing can be done even without a source of mains power. This is especially useful if testing has to be done in the field or in a very busy lab.

Advanced connectivity

XJLink have variable signal termination, so they 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.

Simple DLL API interface

The hardware can be sold separately from the software, with a simple-to-use DLL API interface. We can craft the API to meet whatever needs you have for the system.
