Question
We have found some changes on pages 7 & 8 of the old UG-123 (attached). For
this old version, you could enter the frequencies instead of the CLK values. Is
there a tool for calculating CLK1, CLK2, etc? (otherwise they would write a
Matlab-Script). It would make the calculations slightly easier.
Answer
It was found to be more useful for the user to decide the DEVIATION,
DEV_OFFSET, CLK1, CLK2, and STEPS, and then have the software calculate the
resulting frequencies and times. This is in the latest software:

If you want to go the opposite direction, you will need to write a script or
manually do the calculations. The relevant formulae are equations 9 – 15 in the
ADF4158 data sheet.
