What crystal for a ATMega328P-AU 8MHz 3.3V

Does anyone have a part number for a surface mount crystal for a 8MHz 328P-AU? Something that is known to be good and also the values of the caps used with the crystal. I know about the internal osc but I need the frequency stability of the crystal.



XC1776 from digikey. 16MHz, use the system clock divide by 2 prescaler to get 8 MHz.
You can see one here, with 22pF caps. I think those were 1206 size, 0805 size work as well.

These little guys work well also
A 16 MHz version can be seen here:
