![]() ![]() I ordered some oscillators and some other parts to make it easier to tweak voltage than by replacing resistors. Not all chips are created equal some will require more voltage and some will require less but if we can get a good sample going I think we can create a base line to go off of. As far as Voltages/frequency I plan to post a chart up of what works what frequency, of course your mileage will vary. Sorry I missed your post, but yea thats that how it would go. Now assuming I'd need a hot air rework station like this one to complete all this? Now I assume I'll have to replace a resistor or 2 to increase the power from 1.05v to 1.15v (or more?) and at what point (of OSC MHz increase) does the voltage have to be increased? Then I could replace the 12Mhz crystal oscillator with either.Ī 14.31818MHz OSC which would produce approx 397Mh/sĪ 16MHz OSC which would produce approx 444Mh/sĪ 18.432MHz OSC which would produce approx 511Mh/s I could then add heatsinks and such to transfer more heat as needed? ![]() This would prevent shorting on the now exposed PCB? Then I'd have to put down a very thin layer of an electrically insulating, but thermal conducting material. So first I should piss off the solder mask for better conductivity? like so. Rightio, so I'm just here to dumb this down a bit (he he he ) and make this a touch easier to understand for the layperson that wants fiddle with this sorta thing. Your going to need a hot air gun at the very least if you want to replace these with any success. Replacing just the crystal without any other changes put the board over the current limit for usb spec and at 1.05 volts it will not be anywhere close to stable. The one I am currently using is I also have a 18.43 and 20mhz version but have yet to test as I'm waiting on power supply parts. The ones in the above link meet these specs. Check the data sheet to make sure it's pin compatible. The only ones that are pin compatible are the Tri-state versions with the OE pin. Specs need to be: 3.3v, 5mm X 3.2mm, 4 lead SMD. Here is a filtered list of oscillators on digikey of different freqencys ![]() I'm a little thrown off by some of the specifics of the thread, and I want to get in start soldering (I'm awesome with a soldering iron ) So can somebody link me to the 14mhz and the 16mhz crystal oscillator that can be used? can I just buy any old 4 pin crystal?
