NCO Frequency modualtion

Hi, I am trying to make a frequency sweeper with an NCO. Can anyone tell me how the modulation input into the NCO works. I want it sweep from 1MHZ to 48MHZ? Thank you in advance.

Hi,

you can either precalculate the values and insert in LUT then run an address

scheme. Or you can compute that on the fly in software or in hardware. The choice is yours.

A counter alone can't do that.
