Hi Kristoffer,
thank you very much. I got other crystal model 406 from CTS company. It has 48MHz fundamental frequency and it works perfectly. Maybe it is a good idea to update datasheet with information, that it is not possible to use crystal with 48MHz on the 3rd overtone. Only crystal with 48MHz on fundamental frequency can be used.
Until now I had not idea, that there exist something like crystal with 3rd overtone frequency ;-)
