Oscillators v Crystals

jfurness

Oscillators in a modern circuit - are Crystals still the most accurate way of timing?

    If cost is an issue, use crystals.  If time to market, oscillators.  If both (wince) I would go with a crystal circuit.

     

    Note: this does not apply to chips that appear to give you a choice between crystals and oscillators.  Be sure you read the data-sheets thoroughly image

    Well I agree...if cost matters do select the xtal..

     

    It is always better to read the data sheet thoroghly before chossing either..

     

    I have notices that In cases, oscillator are better than xtal where timing is crucial eg. if you are using 10/100Mb network phy use..XTAL as input clock source..but if using 1Gb network phy I would suggest to use oscillator..

     

    If you are intended to desing more robust system use " Oscillator "..

     

    Also if you are designing some server type application I would suggest Oscillator
