PIC XT oscillator question.
Ok, i'm hoping there is someone on these forums who can help me here. My problem is this: I am trying to clock a PIC18F252 at 40Mhz, but can't seem to find a way to do so. I can't find non SMD 40Mhz ceramic resonators. I can find 40Mhz crystal oscillators, but that is not their fundamental frequency. They are all designed to operate on a third harmonic and i have no idea how to do this. What about a 10Mhz crystal + the PLL? I don't understand that either? Anybody have any advice as to how i can get 40Mhz? It must be FIRST legal. Also, i have never designed anything this high frequency before, will 40Mhz even work with through hole?
