Abstract:
1. A radio frequency (RF) receiver with frequency planning comprising: an analog receiver having an input for receiving an RF input signal, and an output for providing a digital intermediate frequency (IF) signal; a digital processor having a first input for receiving said digital IF signal, a second input for receiving a clock signal, a signal output for providing an IF output signal, and a control output for providing a clock control signal; a clock synthesizer having an input for receiving said clock control signal, and an output for providing said clock signal; and wherein said digital processor controls said clock synthesizer to adjust a frequency of said clock signal to one of a predetermined number of frequencies within a predetermined frequency range in response to said clock control signal by selecting said frequency based on whether a spur, generated when said clock signal mixes with a signal generated in a magnetically coupled circuit, falls within a desired range.
