Isolation Adapter

Isolation Adapter


The Blackhawk Isolation Adapter is a device that connects between your JTAG Emulator and the JTAG connector on your target board. The adapter is designed to minimize and protect connected devices (PC/Emulator/Target) from ground loop voltage, harsh environments, and untested designs. The Isolation Adapter supports 3.3-5.0v targets and is available with standard TI 14-pin or compact TI 20-pin JTAG connections.

The Blackhawk Isolation Adapter provides backwards compatibility to standard TI debug connections. Therefore the adapter is compatible with TI XDS510 or XDS560-class JTAG emulator, new or old. However, it is recommended that you check with the emulator manufacturer.

Features & Specificiations

  • Supports I/O voltages of 3.3V/5.0V targets
