Hi,I am doing the board replica of Cyclone IV GX EP4CGX15 development board. I am changing the IC from EP4CGX15(F169 pins) to EP4CGX22(f324 pins) because in my application i require more IOs. Does this IC(GX22) is compatibality with GX15 in terms of clocks, vcc etc. For your ref GX15 has 125 mhz, can this same crystal be used for EP4CGX22(F324).
