Overview

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 new, 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.

Blackhawk also has Pin Converters available to match your configuration of emulator and target connections.

Compatibility

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.
