Method and System for Coexistence in a Multiband, Multistandard Communication System Utilizing a Plurality of Phase Locked Loops

A wireless transceiver, comprising:

• a processor configured to determine a desired frequency of operation and a frequency of a spurious emission based on the desired frequency of operation;
• a plurality of phase locked loops configured to generate a plurality of signals based on the desired frequency of operation;
• a multiplexer configured to select a selected signal from among the plurality of signals;
• and
• a divider configured to reduce a frequency of the selected signal to generate a divided frequency signal, wherein the processor is further configured to cause the multiplexer and the divider to select the divided frequency signal to avoid the spurious emission.

A wireless transceiver, comprising:

• a processor configured to determine a desired frequency of operation and a frequency of an interfering emission based on the desired frequency of operation;
• a reference frequency generator circuit configured to generate a reference frequency;
• and
• a transmit frequency synthesizer configured to generate the desired frequency of operation within a transmit emission mask based on the reference frequency, wherein the processor is further configured to adjust the reference frequency to avoid spurious emissions within the transmit emission mask.
