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

2005-07-03 by Pigeon

Interesting.
So HC49 is the package/case type?
I didn't see any hc49-hs on digikey.. just hc49 hc49/51 hc49/UA hc49/us
like:
http://rocky.digikey.com/WebLib/CTS/Web%20Data/MP%20Series.pdf
Also, would I need any caps with this?
Sorry, I have been reading a bunch on this.. and now everything is meshing together...

If you don't use the internal oscillator and there is not lots of boards
involved,
then use a crystal for best results. Resonators are good if you are trying
to save a few
cents a board. I use the HC49-HS types (low profile).
