Integrated circuit for processing multi-channel radio signal

An integrated circuit for processing a received multi-channel radio signal comprising:

• an analog signal processing unit for generating a local signal based on a reference clock signal supplied from an external oscillator capable of changing an oscillatory frequency and selecting a desired channel from the multi-channel radio signal using the local signal;
• a digital signal processing unit for receiving the reference clock signal as an operation clock signal and performing digital demodulation of a signal of the channel selected by the analog signal processing unit;
• and
• a control unit for designating a frequency to be oscillated by the external oscillator in response to the channel selected by the analog signal processing unit.

An integrated circuit for processing a received multi-channel radio signal comprising:

• a selector unit for receiving a plurality of different reference clock signals from an external oscillator and selectively outputting any one of the reference clock signals;
• an analog signal processing unit for generating a local signal based on any one of the plurality of reference clock signals and selecting a desired channel from the multi-channel radio signal using the local signal;
• a digital signal processing unit for receiving the reference clock signal output from the selector unit as an operation clock signal and performing digital demodulation of a signal of the channel selected by the analog signal processing unit;
• and
• a control unit for controlling the signal selection by the selector unit in response to the channel selected by the analog signal processing unit.
