Question about Hittite PLL Software 1.15 and Initial and Step Frequency

Hello all,

 

I am using the Hittite PLL version 1.15 to design a frequency synthesizer.

 

Regarding the models already done, in "PLL with integrated Microwave VCOs" folder,

 

Why all examples are using 1.7 GHz as initial frequency and 100 MHz as frequency step in the "Transient Response Setting" tab?

Is this random or there is a reason? why don't use the VCO frequency?

 

To get to the point, how do you choose the Initial Frequency and Frequency Step settings?

 

Many thanks,

 

Regards
