Patent ID: 8633739

Claim:
A frequency divider system, comprising: a phase multiplexer configured to receive a plurality of signals having different phases, the phase multiplexer, in response to a phase select signal, further configured to select first and second signals from the plurality of signals, the first and second signals having different phases, the phase multiplexer further configured to generate a first output based on the selected first signal and a second output based on the selected second signal, the plurality of signals having sequentially increasing phases, the sequentially increasing phases increasing by an increment, the increment being approximately 45 degrees, the first and second signals having a phase difference that is a multiple of approximately 45 degrees, other than 180 degrees; a first frequency divider configured to receive the first output of the phase multiplexer and produce a frequency-divided signal; and a phase controller configured to receive the frequency-divided signal and a non-frequency-divided signal representative of the second output of the phase multiplexer, the phase controller further configured to produce the phase select signal in response to the generation of the second output of the phase multiplexer and based on the frequency-divided signal and the non-frequency-divided signal.
