geokonst Posted November 25, 2010 Report Share Posted November 25, 2010 Hi, I was wondering if it's possible to replace papillo one crystal with a 50MHz one. Planning to use hot air station. Any reason why this wouldn't work? Link to comment Share on other sites More sharing options...
Jack Gassett Posted November 25, 2010 Report Share Posted November 25, 2010 Hello, Sure, it is no problem to replace the crystal with a 50Mhz one. A hot air rework station will do the trick, but I also do it fairly often with just a soldering iron. If you put plenty of flux on the pads you should be able to heat up one side and then switch to the other side, keep switching back and forth until the part gets warm enough to slide off the pads. Just be careful not to use to much heat as it can damage the pads. Another option is to keep the 32Mhz crystal on the board and use a DCM (Digital Clock Manager) to change the 32Mhz clock to a 50Mhz clock inside your project. I have recorded a tutorial about how to do this. http://www.gadgetfactory.net/?main_page=wordpress&p=178 Jack. Link to comment Share on other sites More sharing options...
geokonst Posted November 25, 2010 Author Report Share Posted November 25, 2010 Thanks. I was thinking to replace the crystal because I need an 150MHz clock and don't want to cascade 2 DCMs. Link to comment Share on other sites More sharing options...
