    Hello Giora,

    The LMK04828 is only configured for distribution mode, not clock generation mode. These two modes have different input clock ranges, please see the screen shot below

    In the bottom box we can see the Fin in distribution mode is actually 0.001 MHz to 3100 MHz, which will support the clock speed you want.

    Best,

    Eric
