thnx alot..............................
ma main problem is i can not find the exact pll ic and a programmable divider ic...as i have to make 100 channels out of 2MHZ to 12MHZ....at any time by using divider i could select any channel say i want to select 10.7MHZ(for example)
thnx...but i can not use a crystal of value between 2MHZ and 12MHZ as it will produce a notch in the desired band of frequencies.....and it ll not be easy to remove
now i have decided to use a crystal as without crystla it is not easy to achive.......please guide me what value of crystal i shud choose...and pll IC and divider ic which gives me a step size of 100khz.....as i have to make hundred channels from 2MHZ to 12 MHZ........
guyz thnk 4 ur help
i need to construct a vco that generates a range of frequencies from 2 MHZ to 12 MHZ with a step size of 100khz..............
we can tune the vco on a fixed frequency and can use the divider circuits for this purpose.
but the problem is i dont have any idea from where to start...note:i cant...
