I'm using the HMC832 in the conditions fixed in the datasheet p34 figure 52 (loop filter design).
We choose the loop filter type 1 in the table12. The Fxtal is 40Mhz.
I succeed in programming the module correctly and it is always locked.
But for some frequencies, it is not exactly locked at the right frequency.
For example, at 80Mhz the output is 81.5Mhz.
We use an Xtal=40Mhz and we noticed that it happened at 40/80/160Mhz.
Thanks for your help.
