Re: [AVR-Chat] What crystals/resonators do you'll use?

Sounds good.
Just to double check (because I am about to make an order from digkey) (and my last order.. I had some wrongly ordered parts)
For the Caps, I would use:
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328204&Row=415594&Site=US
And for the Crystals, I would use(might as well buy a couple of each while I am ordering..):
8MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328146&Row=519024&Site=US
4MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328454&Row=519334&Site=US
10MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328651&Row=82414&Site=US
12MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328557&Row=82970&Site=US
16MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328694&Row=83051&Site=US
20MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328806&Row=82469&Site=US
25MHz
http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=328887&Row=82471&Site=US
Basically, I just make sure each crystal has these properties:
Load Capacitance 18pF Package / Case HC49/US
Does all this sound about right?
thanks
Lee

Must be the hc49/us. They are shown on the sparkfun website. They
are the mid sized ones.

>Also, would I need any caps with this?

I use 2x15pf caps only because I have lots of them.
The more suitable may be 18-22pf.
