Re: Some basic load measurements

There are no mixers within the Si5351A. Whatever generated is done by fractional synthesis from the crystal clocks. There is another slightly different frequenc output that drive the mixer detectors. This is necessary as there are no antialiasing filters.Sent from my Samsung Galaxy smartphone.

Is that something that can be controlled in this source chip?Yes, indirectly, by changing amplitude of signals into the mixer(dominant distortion contributor).
