Tool/software:

There are significant harmonics on the LMX2694EPEVM when using the clock divider circuit. Is this to be expected or am I not using the correct settings?

Just wondering if I'm being stupid and the output is trying to be a square wave and not a sine wave although it has even harmonics?

Hi Ross,

Divided down output is square wave, so output is harmonics rich.
