  • FM radio frequency plan using programmable output counter
    Patent number: 8254849
    Abstract: An FM radio with a wide frequency range operates in a cell phone without interfering with the VCO of the RF transceiver. The FM transceiver generates a VCO signal whose frequency varies by less than ±7% from the midpoint of a narrow first range. A synthesizer signal is generated by dividing the VCO frequency by a first divisor such that the synthesizer frequency varies over a lower frequency second range. The VCO frequency is also divided by a second divisor such that the synthesizer frequency varies over a third range. The upper limit of the second range falls at the lower limit of the third range. The lower limit of the second range is 85.5 MHz and the upper limit of the third range is 108.0 MHz. By also using a third divisor, a synthesizer signal with a range of 76-108 MHz is generated from the narrow first frequency range.
