Fractional-N frequency divider has wide range of application. One example can be channel selection in multichannel radio receivers. The fractional division technique achieves fine frequency resolution and fast switching speed while possessing low phase noise level and reference frequency feed through suppression and allows the use of a higher input frequency, larger loop bandwidth and thus, reduces the settling time.

Our design supports wide range of Fin and Fdiv based on the timing closure of a given process. One example for number is given in feature list for better illustration
