J-Link Isolators

The J-Link SWD Isolator can be connected between J-Link and any ARM-board that uses the standard 20-pin 0.1" male connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application. It is also useful to protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another typical field of application is the development of products with sensors or other analog circuitry, in which case the target hardware is protected from electrical noise originating from the development PC.

The J-Link SWD Isolator is compatible with J-Link BASE, J-Link PRO, J-Link ULTRA+, J-Link PLUS and Flasher ARM.

The J-Link JTAG Isolator can be connected between J-Link and any ARM-board that uses the standard 20-pin JTAG-ARM connector to provide electrical isolation. This is essential when the development tools are not connected to the same ground as the application. It is also useful to protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another typical field of application is the development of products with sensors or other analog circuitry, in which case the target hardware is protected from electrical noise originating from the development PC.

The J-Link JTAG Isolator is compatible with J-Link BASE, J-Link PRO, J-Link ULTRA+, J-Link PLUS and Flasher ARM.

The J-Link USB Isolator can be interconnected between J-Link and the host PC. J-Link is connected via USB to provide electrical isolation of the J-Link from the host (PC) side. This is essential when development tools are not connected to the same ground as the application. It is also useful to protect the development tools from electrical spikes as overvoltage may occur when using low-budget USB hubs.

The J-Link USB Isolator is compatible with all J-Link models and Production Programmers that use USB.
