Patent ID: 7471940

Claim:
An integrated receiver, comprising: analog receive path circuitry coupled to receive an RF signal spectrum and configured to mix a channel within the RF signal spectrum down to a lower frequency to produce down-converted signals, the analog receive path circuitry being configured to use a mixing signal during operation, and the RF input signal spectrum comprising a plurality of channels; digital conversion circuitry coupled to receive the down-converted signals and configured to produce digital output signals, the digital conversion circuitry being configured to use a digital sampling clock signal during operation; digital circuitry configured to receive and to digitally process the digital output signals, the digital circuitry being configured to be clocked in operation using a digital clock signal; a clock system configured to receive an oscillation signal and to generate the mixing signal for the analog receive path circuitry, the sampling clock signal for the digital conversion circuitry, and the digital clock signal for the digital circuitry from the oscillation signal so that the mixing signal, the sampling clock signal and the digital clock signal have a common base clock signal; wherein the analog receive path circuitry, the digital conversion circuitry, the digital circuitry and the clock system are integrated within a single integrated circuit.
