    Hi,

    I just have quick question regarding the generation of a clocking signal. I was wondering if the following circuit would be sufficient enough to generate a 10 Mhz signal, given the correct R and C values?

    I just wanted to check before i went ahead and bought any components. If this circuit isn't able to, then any help would be appreciated.

    Thanks.

    What kind of stability are you looking for?
    The simplest solution is to purchase a 10MHz crystal oscillator module (XCO). Apply power and you get xtal controlled 10MHz output, stable to 1:1000000.

    Couldn't be easier, and it's cheap too.
    An op-amp circuit could accomplish that frequency, but not without careful component choices and attention to design and layout, and you still won't get anywhere near the stability of the XCO.

    Thanks for the help guys. Would someone please be able to link me to one of these oscillators? Thanks.
