Abstract
Integrated circuit devices include programmable dividers, such as fractional-N dividers, which can utilize multi-modulus dividers (MMD) therein. A multi-modulus divider includes a cascaded chain of div2/3 cells configured to support a chain length control operation that precludes generation of an intermediate divisor in response to a change in value of a chain length control byte P<n:0> during an update time interval and may even fully turn off one or more of the div2/3 cells not participating in a divide-by-N operation, where N is a positive integer greater than one. The div2/3 cells are configured to include a modulus input terminal and a modulus output terminal and the chain length control operation is independent of the magnitude of the signals provided to the modulus input terminals of the div2/3 cells.
