Hello,
I after successfully configuring an LMX2572LPEVM board for he output frequency of 915 MHz using an external 100MHz reference signal, I attempted to populate/change the reference signal configuration s described in the guide for a differential crystal oscillator. The oscillator used is LMK60E2-100. On a network analyzer, I see peaks at 780.7MHz, 1.57GHz and 2.34GHz. I tried changing the default settings (wich are supposed to produce a 1500MHz output) but it didn't cause any change in the output.
Are there any other hardware configurations I need to change or any registers that I need to program?
Thank you for your help.
