This paper examines the nonlinear dynamics of an
alias-locked loop (ALL) which uses an aliasing divider instead of
a traditional frequency divider in the feedback loop of a phaselocked
loop. A nonlinear model of the ALL is developed and
used to study the global and local nonlinear dynamics of the
system. In the global dynamics, we see disconnected regions of
stability, which arise as a direct result of the aliasing operation.
In the local dynamics, we see how the orbits observed have a
particular dependence on the ratio of sample and reference
frequencies.
