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

Hmm.. because I would rather have something super simple.. and high quality, I like the idea of the

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)

Pull up a data sheet. VDD and GND are the power supplies for the oscillator.
OUT is the oscillator output, goes to the AVR's input pin.
OE is output enable, you'll tie that low or high to make the oscillator run.

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 :/

They were chaining the clocks. Workable, but I would caution that you are begging for trouble.
