摘要： An integrated circuit (IC) includes a clock circuit, a processing module, and processing circuitry. The clock circuit is coupled to produce a digital clock signal. The processing module is coupled to determine whether a harmonic component of the digital clock signal having a nominal digital clock rate is within the frequency passband and to provide an indication to the clock circuit to adjust its rate from the nominal digital clock rate to an adjusted digital clock rate when the harmonic component of the digital clock signal is within the frequency passband. The processing circuitry is coupled to process, at the adjusted digital clock rate, the data to produce processed data having a rate corresponding to the nominal digital clock rate and to interpolate, at an interpolation rate, the processed data to produce interpolated processed data having a rate corresponding to the interpolation rate.

摘要： An integrated circuit radio transceiver and method therefor includes an integrated circuit radio transceiver operable to provide pre-distortion settings that correspond to specified analog transmit path gain levels. Further, a change in gain is provided solely through digital gain when the new gain is within a specified range. If the gain change is not within the specified range, the gain is provided by a new transmit path gain module and, if necessary, with additional digital gain. Additionally, a new pre-distortion setting is applied to correspond to the new analog transmit path gain setting.
