XJLink — USB 2.0 to JTAG adapter
XJLink is a small, portable, USB hardware device that provides a high speed interface (480Mbps) to the JTAG chain on a circuit board.
The small, lightweight design means the XJLink can easily be moved to the Unit Under Test (UUT). Advanced features, like its 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 its USB plug-and-play ability.

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
- High speed USB 2.0 interface, backwards compatible with USB 1.0 & 1.1.
- USB bus-powered (no external PSU).
- TCK clock frequencies up to 50MHz.
- Adjustable JTAG signal termination.
- Automatic signal skew control.
- Handles different cable and board configurations.
- Can supply power to the target board
through the JTAG connector
(3.3V, <100mA). The power can be switched on and off programmatically. - JTAG signals are +5V tolerant.
- Spare signals on JTAG connector can be used to control other items —
e.g. hold a board in reset / turn on a PSU. - Runs on Windows 2000 / XP / Vista.
- USB compatible: No need to open the computer to install the hardware.
- Software configurable pinout: Can be configured to Xilinx parallel, Altera ByteBlaster ®, ARM MultiICE ®, or any other pinout currently in use, via a 0.1mm pitch 20-way header.
- Simple DLL API interface: includes commands such as tmsReset() irScan() drScan() etc.
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.
The API header file is available for download: XJAPI.h
