Abstract
A system for reducing self interference in a mobile terminal is provided. In general, the system includes a receiver including downconversion circuitry that converts a received radio frequency (RF) signal to a downconverted signal using one or more local oscillator frequencies. The downconverted signal is processed by digital circuitry clocked by one or more clock signals to obtain information from the RF signal. The local oscillator frequencies are provided by a frequency synthesizer as a function of an output frequency signal of a phase lock loop. Divider circuitry operates to divide the output frequency signal of the phase lock loop to provide the clock signals.
