    摘要： A radio frequency integrated circuit (RFIC) includes a low noise amplifier that amplifies an inbound radio frequency (RF) signal to produce an amplified RF signal. A down conversion module converts the amplified RF signal to a down converted signal based on a local oscillation. An analog to digital conversion (ADC) module coupled to convert the down converted signal into a digital signal. A baseband processing module converts the digital signal into inbound data, wherein at least one function of the baseband processing module is clocked by a plurality of baseband clock signals A clock module produces the plurality of baseband clock signals, wherein the clock module detects an interference condition when frequency dependent noise components associated with at least one of the plurality of baseband clock signals are inside a frequency band associated with the inbound RF signal, and spreads the spectrum of the at least one of the plurality of baseband clock signals when the interference condition is detected.

    摘要： A Voice-Data-RF IC includes a baseband processing module, an RF section, and an interface module. The baseband processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. The RF section converts an inbound RF voice signal into the inbound voice symbol stream, converts the outbound voice symbol stream into an outbound RF voice signal, converts an inbound RF data signal into the inbound data symbol stream, and converts the outbound data symbol stream into an outbound RF data signal. The interface module provides coupling between the baseband processing module, the RF section, and with off-chip circuits.
