XJIO Board
The XJIO board is an expansion unit that enables you to improve the test coverage for a Unit Under Test (UUT) by verifying the signals right through to the external connections. It will integrate with your XJTAG test system to provide access to otherwise inaccessible areas of your circuit.
With a range of digital and analogue I/O pins on the board, you can improve fault isolation, verify power rail levels, and dispense with costly custom test jigs - even for non-JTAG boards.

Digital I/O
With 208 bidirectional digital I/Os, the XJIO board has been developed for maximum connectivity. The I/Os are all 5V tolerant. The default logic level is 3.3V, or you can re-configure the I/Os, in blocks of 16, to use any user-generated voltage between 3.3V and 1.8V.
Analogue Testing
The XJIO board has 16 analogue I/Os (8 inputs and 8 outputs). These are all controllable via the JTAG interface. The on-board 3.3V ADC devices enable basic analogue measurements - e.g. testing a power rail is within limits. The 3.3V DACs allows for UUT analogue inputs to be stimulated, improving test coverage of the target board.
Expandable
If more I/Os are required, the XJIO boards can be daisy-chained together via the reconfigurable external JTAG connector to reach the required density. All the connectors on the XJIO board are standard IDC, for economical and efficient cable assemblies.
Power Supplies
You can power the XJIO board from USB, for quick and portable test setup. Alternatively, if you need more than 80mA of current, there is a connector for a standard 12V power supply.
User Interaction
The switches and LEDs enable additional test control, allowing you to develop a complete and repeatable test solution.
Software
You can use the XJIO board with the whole XJTAG product range.
