The datasheet does say that you can use XT crystal mode with x16 PLL, and c= rystals over the range of 4 - 7.5MHz, provided the maximum operating freque= ncy of 120MHz is met (ref table 17-1 of the Rev C data sheet). So he is wit= hin the operating parameters of the PLL. --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
