Modulus divider with deterministic phase alignment
Abstract:
An apparatus includes a plurality of latches and a plurality of logic gates. Each latch may be setable and resettable. The logic gates may be connected to the latches to form a multi-modulus divider that generates an output clock signal by dividing an input clock signal in response to a command signal. Each latch may be commanded into a corresponding initial state while the command signal is in an initialization state. Each latch is generally free to change states while the command signal is in a run state. A modulus division operation of the multi-modulus divider may start upon an initial edge of the input clock signal after the command signal changes from the initialization state to the run state.
