Patent ID: 8731501

Claim:
Integrated receiver circuitry comprising: on-chip mixer circuitry configured to receive a radio frequency (RF) signal and to mix the RF signal with a local oscillator (LO) signal to produce a downconverted signal; at least partially on-chip LO circuitry coupled to provide the LO signal to the mixer to produce the downconverted signal; at least one on-chip processing device configured to receive a RF tuning control signal representative of a selected radio frequency, the processing device being coupled to the LO circuitry and coupled to control the frequency of the LO signal with an oscillator control value operable to downconvert the selected radio frequency without consideration of a crystal oscillator and without consideration of an external off-chip timing reference, the oscillator control value being selected based at least in part on measured temperature; and on-chip memory circuitry coupled to the at least one processing device, the memory circuitry containing oscillator control information that includes the oscillator control value corresponding to the selected radio frequency at the measured temperature; wherein the at least one processing device is configured to access the memory circuitry and to select the oscillator control value based at least in part on the measured temperature, and is further configured to output a digital display signal based on the selected radio frequency without consideration of a crystal oscillator and without consideration of an external off-chip timing reference, the digital display signal containing digital display information that represents the identity of the radio frequency of the downconverted signal.
