5.8 XDP Tools to ITP700Flex Adapters
XDP tools require an adapter to mate to the ITP700Flex debug port. Additionally there
may be requirements of changing terminations on some signals. Below is a list of
termination resistance changes for most XDP based tools. This list is not meant to be all
encompassing but rather a guide of items that will need to be changed in all cases.
Please contact your vendor of choice for the most recent guidelines for all changes
required to use their tool.
• TCK - Change termination resistance to 51 ohm 5%
• RESET_IN# - Isolation resistor change to 1K ohm 5%
• TDI - Change termination resistance to 51 ohms 5%
• TMS - Change termination resistance to 51 ohms 5%
5.9 Mechanical Specifications
The following diagram illustrates the exterior dimensions of the ITP700Flex hardware
as well as board level height restrictions and cable egress.
Cap all vias near the ITP700Flex connector pads in compliance with the Intel Design For
Manufacturing Guidelines for capped vias.
