Ultra low in-close phase noise also allows wider loop bandwidths for faster frequency hopping. t he fractional-n PLL contains a built-in linear sweeper function, which allows it to perform frequency chirps with a wide variety of sweep times, polarities and dwells, all with an external or automatic sweep trigger. in addition the fractional-n PLL has a number of auxiliary clock generation modes that can be accessed via the GPo .
