Abstract
A multiple-modulus divider and an associated control method are provided. The multiple-modulus divider includes a divisor loader, a multiple-modulus dividing circuit and a modulus controller. The divisor loader downloads a divisor when a download signal indicates a start of a division period. The multiple-modulus circuit includes a plurality of cascaded divisors, and provides an output frequency according to an input frequency and the divisor. The dividers respectively output a plurality of modulus output signals, and each is operable under either a close-loop state or an open-loop state. The modulus controller selects and controls one of the dividers according to the divisor, and ensures the selected divider is maintained at the open-loop state when the division period ends. The download signal corresponds to one of the modulus output signals.
