Re: LVTTL in virtex II Pro
Hi,
In my design ALL VccAux are 2,5V and ALL VCCO are 3.3V.
"Before and during configuration, all configuration I/O pins are set for the
LVCMOS25(12mA, fast slew rate) standard when VCCO is 2.5V. It becomes LVCMOS33
(16mA, fast slew rate) when VCCO is 3.3V." (VirtexII-Pro Platform User Guide - UG012 pag.286) (See also page 287 that has a table concerning this matter).
You can also take a look to page 288 where a "Mixed Voltage Environments" operation is explained.
Hope this helps.
