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

2005-07-04 by Pigeon

Hmm.. because I would rather have something super simple.. and high quality, I like the idea of the
crystal clock oscillator
http://rocky.digikey.com/WebLib/Epson/Web%20Data/SG-51,531%20Series.pdf
but my question is.
I see
pin1: 0E
pin7: GND
pin8: OUT
pin14: Vdd
but what pins go to what? (do I need any external caps/resistors)
I have seen a schematic that had xtal 1 go to the crystal clock oscillator.. then xtal2 go to another avr's xtal 1.. but that isn't what i want.
I guess the pdf of this schematic expects an expert to be reading it :/
what do you'll think?

I will go with the 33pF like Kathy.

Even if the 27pF was perfect'', this would still be a better solution that going with ceramic resonators?

"better" is hard to define. Resonators are less accurate. If you don't need this much accuracy, then you're wasting money.


Oh yeah, I was thinking about going with something like an Crystal Oscillator Modules.. but I couldn't find these on digikey.. How much do these normally run and where can I get a dip ver?

Looks like $1.50 and up
