datasheet lists this as 3.3v nominal, min 3.14v. any chance this could work at 2.5v for direct fpga interface?
Nope.. sorry. Support for lower I/O voltages is an increasingly common and important requirment though so I suspect it'll be supported in future parts.
DaveD is right; I looked sometime ago into it and 2.5V is a little bit on the edge.
Even though I could still get clock on the output - it was lab setup.
is pretty likely system may fail with too small voltage.
I think I lost completely clock around 2.0 ... 2.2V
