J-Link Isolators
SEGGER isolators provide easy target-side or host-side isolation for reliable use in different fields of application.
Overview
Development and manufacturing environments contain many variables that may be hazardous to the proper operation and longevity of development tools, such as noise, electrical spikes, transient overvoltages, and ground loops. With its line of isolators, comprising the JTAG, SWD, and USB Isolator, SEGGER offers target-side and host-side electrical isolation for the Flasher, J-Link, and J-Trace families.
JTAG Isolator
The JTAG Isolator Box is inserted into the connection of a J-Link or Flasher and a target board to provide electrical isolation. This is essential when the development or production tools are not connected to the same ground as the application. The JTAG Isolator uses high speed digital isolators that allow a very low propagation time between input and output.
SWD Isolator Box
The SWD Isolator Box is inserted into the connection of a J-Link or Flasher and a target board to provide electrical isolation. This is essential when the development or production tools are not connected to the same ground as the application. The SWD Isolator uses high speed digital isolators that allow a very low propagation time between input and output.
SWD Isolator Plugin
The SWD Isolator Plugin can be plugged directly into the target interface of a J-Link or Flasher to provide electrical isolation on the target interface side. This is essential when the development or production tools are not connected to the same ground as the application. The SWD Isolator uses high speed digital isolators that allow a very low propagation time between input and output.
USB Isolator
The USB Isolator can be interconnected between J-Link or Flasher and the host PC. J-Link or Flasher are connected via USB to provide electrical isolation of the J-Link or Flasher 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.
