ABSTRACT:
Aspects of a method and system for using a Bluetooth® PLL/LO to drive FM Transmit, FM Receive, Bluetooth, and NFC functions. A Bluetooth® PLL/LO may be utilized to generate Bluetooth® signal that comprise I and Q components for use in Bluetooth® communication. The Bluetooth® signals may then be utilized by a DDFS to generate FM radio I and Q signals for FM radio reception and/or transmission. The Bluetooth® signals may also be utilized by a second DDFS to generate signals for near field communication (NFC) transmission and/or reception. The Bluetooth® signals may be kept at the same frequency, or reduced in frequency, for use in clocking the DDFS. A frequency word may also be utilized to clock the DDFS. The outputs of each DDFS may be a constant frequency while the inputs to each DDFS may vary in frequency.
