I'm working with the PLL VCO HMC830.
I want to use a look-up table (LUT) for manual calibration, as decribe in "Frequency Hopping with Hittite PLLVCOs Application Note" (attached) (https : // www . hittite.com/content/documents/application_notes/Fast_Frequency_Hopping_Application_Note.pdf).
It should have equivalence between the desired frequency and capacitors switches configuration (Reg 10h Register Tune VCO).
I wonder if somebody already have those data and could provide it.
Thank you very much in advance.
I have a doubt regarding the table with the values of the switch capacitors.
I set the HMC830 without auto-calibration.
Then I printed the registry values "Reg 10h VCO Tune Register" to various frequencies with a step of 10KHz in order to see that frequency changes occur Reg10 value. (see attached below)
As shown in the table, there are some "jumps" in the Reg10 values.
I have seen that there are 6 jumps and are always 32 to 5 on the previous value (see column "changes").
My questions are:
Will they always be 6 jumps?
Is the jump occurs in the same registry value?
Thank you very much for your help.
