Answers Database Cable - The Parallel Cable III (JTAG Cable) will accept 5V or 3V or 2.5V as power supply. Record #4116 Product Family: Software Product Line: CPLD Implementation Product Part: jtag Problem Title: Cable - The Parallel Cable III (JTAG Cable) will accept 5V or 3V or 2.5V as power supply. Problem Description: Urgency: Standard General Description: Can a board supply of 3V or 2.5V be used as the power supply of the jtag cable? Solution 1: The jtag cable will accept 5V or 3V or even 2.5V as the power supply. Even through the cable can accept 2.5V, one thing to bear in mind is as of Q1, 1999, Xilinx do not have any devices that can be configured at 2.5V yet. That is the Virtex parts and the 4000XV have Vccio at 3.3V so the cable needs to be driven at this level as well. End of Record #4116 - Last Modified: 12/10/99 08:55
