    Default Crystal vs Resonator

    I'm constructing a circuit for outdoor use. I was thinking about using a resonator to save space vs. a crystal/capacitor combo.

    Any advantages or disadvantages I need to consider?

    Hi Dynamo,

    If there are no critical time issues ... no problem. just have a look at tempco and freq. precision to see what.

    I'm doing serial @9600, I2C, and OWIN/OWOUT.

    A resonator is good for the above and should save you a couple of capacitors if you select one with internal caps.

    I had two thoughts while laying out the board, save on space AND I believe a resonator is better when there are going to be temperature extremes. Correct?

    Crystals Are Better For Initial Calibration Accuracy And Temperature Stability.

    Resonators Are Typically 0.3% Accurate And 0.1% Temperature Stability, While Crystals Are 0.005% On Both Accounts. In Most Applications, The Resonator Is Adequate However.

    I Have One Project That Has Timers Running Up To 24 Hour Range And Temperature Exposure Of 0-90 Degrees Farenheit And Used A Crystal For Stability.

    Most Projects I Design Are Ok With The Internal Rc Clock.
