WebbFractional-N PLLs are employed in many applications. Compared with an integer-N PLL, a Fractional-N PLL has the benefits of fast locking, fine frequency resolution, and is able to accommodate various reference frequencies. The operation principle of a fractional-N PLL lies in dithering the divide ratios to create a fractional divider.
