Hi All,
I am involved in a new design based on HMC699, I need to generate a 5920MHz signal with a reference input of 20MHz.
I have simulated the system using ADISim PLL and the chip programming assitant Gives me 37 (with other names) for the programming register, but from the datasheet I get A=36 S=0.
Fvco=5920MHz
FXtal=20MHz
N=Fvco/FXtal=296
A=int(296/8)-1=37-1=36
S=296-(8*(36+1)=0
With A=37 the system would not work because it would give S=-8
Could someone tell me what is the correct value? Am I doing anything wrong?
Thanks in advance
Javier
