I know, another question about crystal capacitor values.
I would like to use this crystal in the 20 MHz version to clock an ATmega1284.
According to the crystal's datasheet, it has a load capacitance of 20 pF.
Using the formula \$C = 2(C_L - C_S)\$ and assuming a stray capacitance of 2 pF or 5 pF, I get a value for each capacitor of 36 pF or 30 pF, respectively.
However, this is outside the recommended range for the capacitors of 12-22 pF according to page 46 of the ATmega1284 datasheet.
So, can I even use this crystal, and if so, with what capacitors?
