Suzhou Sirte Microelectronics Co., Ltd. is a technical partner authorized by xjtag (UK).
Xjlink / xjlink 2 is a USB 2.0 to JTAG adapter that provides a high-speed interface (480mbps) to the JTAG chain on the circuit board.
The compact and lightweight design makes it suitable for both the laboratory and the production environment. Because of the license, you can install the xjtag system on any machine at will.
Main advantages
Small and light design makes it suitable for both laboratory and production environment;
Because of the license, you can install xjtag system on any machine at will;
For multiple UUTs, the configuration can be reset to save cost.

Features XJLink XJLink2

Connect up to 4 tap ports of UUT

Xjlink / xjlink 2 includes a license, so that the user's mobile license has more flexibility. You can install the xjtag system on any machine at will.
Configurable JTAG port
Just a simple cable connection to the target system - no additional adapters required. Xjlink 2: connect up to 4 tap ports of UUT.
There is a configurable 20 pin connector on xjlink / xjlink 2 to connect the test system. The pinmap of the JTAG signal can be changed to simplify the process of connecting the xjtag test system and the tested unit. It can be configured with Xilinx parallel ®, Altera byteblaster ®, arm multice ®, or any pin output used with a 0.1mm spacing of 20 pins.
Small & Light
Xjlink / xjlink 2 can work in a portable computer with USB interface, which can provide power for low-power target system, so no main power test can also be carried out. The test will be very useful in the field or when the laboratory is busy.
Advanced connectivity
Xjlink / xjlink 2 has variable signal terminals, so the control board has or does not have signal termination. The advanced auto skew control is the highest frequency you can get from JTAG chains and cables. Xjlink 2: through the voltage value compatibility, users can directly connect more taps.
Simple DLL API interface
This hardware can also be sold separately from the software, with a simple DLL API interface, we can design the API to meet the needs of any system.
The API header file is available for download: XJAPI.h
