Abstract
A method for generating clock signals includes dividing an input clock signal to obtain a first in-phase output clock signal, dividing an inverted version of the input clock signal to obtain a first quadrature output clock signal, delaying edges in the input clock signal to obtain a second quadrature output clock signal, selecting a full-rate output to provide a multiphase output clock in a first mode of operation, and selecting a half-rate output to provide the multiphase output clock in a second mode of operation. The first quadrature output clock signal is a quadrature version of the first in-phase output clock signal. The first in-phase output clock signal and the first quadrature output clock signal are included in the full-rate output. The second quadrature output clock signal is included in the half-rate output and is a quadrature version of the input clock signal.
