We plan to remove the 50Mhz crystal from our design,will it cause any problems with our core MCU(MK60FN1MOVLQ15)

There is a 12Mhz crystal present already and we plan to run the controller with the following modules enabled.

There will be two PLLs used,96Mhz for USB and 150Mhz for normal operations

We plan to use :


USB (with 96Mhz PLL)

SD card

Two UART modules

PWM modules

DMA modules


Thanks in advance,
