Abstract

A programmable divider circuit having an adjustable shift register is coupled to a clock and to an output. The shift register receives a clock signal having a clock signal frequency and outputs an output signal with an output frequency corresponding to a user selected divide ratio of the clock signal frequency. Control inputs are coupled to the adjustable shift register to receive control data for adjusting a length of the shift register, the length of the shift register corresponding to the user selected divide ratio.
