Hi all,
Sorry to ask about analog question, but it 's relative to FPGA too.
Do you know a schematic to do 'Automatic I/O voltage sensing' as XILINX does with the ParallelCable IV.
I am designing a new JTAG interface (USB), and I want to be able to drive correctly the target JTAG signals (3.3V, 2.5V, 1.8V, 1.2V).
Are there any lvttl level shifter device to do this work?
Thanks for your advice.
