currently,i'm dealing with fractional pll,but a problem makes me puzzle.
my design focus on wide tuning range,but it require lots of divider modulus ,how does it get?because the sigma delta output only 8 levels at most.
if expanding divider modulus,how ?
 

what is the meas of 'wide tuning range'?
VCO or divider?
