HI!
How much voltage can I apply to the GCLK pins of Virtex2-Pro are they LVTTL compatible or shoul I use a 100ohm resistor to connect then to LVTLL signals like is sugested for some dedicated configuration pins?
Are the GCLK on banks 0, 1, 4 and 5 of the FPGA? If they are, then if I apply 3.3V to the VCCO pins of that banks than could I apply LVTTL signals to the GCLK pins of that bank?
There are GCLKP and GCLKS. If you don't want to use a clock source with diferential signals then what gclk pin you use, the GCLKP or GCLKS?
