DESCRIPTION

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.
