Features

• Transient voltage suppression for ESD, EFT, and lightning events
• Integrated 10-Ohm series resistors for current limiting
• IEC 61000−4−2 Level 4 ESD protection
• Short 3” cable length between JTAG controller and adapter minimizes performance impact
• Standard 20-pin 0.1” pitch, dual-row header connector compatible with all Corelis JTAG controllers
• One-to-one connectors with clearly labeled polarization for quick and easy installation
• Completely passive protection; no external power supply connection required

Protection against harmful events

The protection adapter is designed to be minimally invasive while helping to protect against ESD, EFT, and lightning events that may harm the JTAG controller. The adapter provides IEC 61000-4-2 Level 4 ESD protection on all TAP signals.

TAP Protection Adapter Pin Definitions

Connecting to the target (UUT)

The TAP Protection Adapter ships with a short 3” 20-pin ribbon TAP Extension Cable (p/n 15463) to connect between the JTAG controller TAP connector and the connector labeled “Controller” on the adapter. Note that the attachment assignments (scan controller side and target side) as marked between protection adapter connectors must be strictly observed to maintain proper functionality.

To connect the TAP Protection Adapter to the target (UUT), follow these steps in the order listed:

• Verify that the target (UUT) is powered off.
• Plug one end of the supplied Extension Cable (p/n 15463) directly into the TAP header of the scan controller.
• Plug the other end of the Extension Cable (p/n 15463) directly into the header labeled “Controller” on the TAP Protection Adapter.
• Plug the target cable directly into the header labeled “Target” on the TAP Protection Adapter.
• Apply power to the target. The system is now ready for use.
