I am working with a mk22fn512cap , and wnated to run it at 120 MHz without using an external oscillator.

1) Since PLL are not connected to the internal sources I dont think I can use the internal ref clocks to get it upto 120?

2) So the option is to use IRC48M. in some posts I read that this is not stable and has some known errata..? Can someone tell me if using IRC48M is the correct/best way to get to run the controller to run at 120 Mhz.
