I read PLL in Ramakant gayakwad reference book where they explained that VCO o/p frequency is N times the input frequency, so my query is we r trying to reduce VCO frequency towords value of Reference frequency so if VCo is producing N times higher frequency then they will never become same, as vco increases N times . In Somebook i read (at wikipedia also ) that Use Divide by N counter between VCO & Phase detector (i.e. in f/b path) but they said that divide counter is optional.
