ABSTRACT:
Aspects of a method and system for enabling simultaneous FM transmitter and FM receiver functions using an integrated Bluetooth Local Oscillator Generator (LOGEN). A Bluetooth® LOGEN may be utilized to generate Bluetooth® signal that comprise (I) and (Q) components for use in Bluetooth® communication. The Bluetooth® LOGEN may then be utilized by a DDFS to generate FM radio (I) and (Q) signals for FM radio reception. The Bluetooth® LOGEN may also be utilized by a second DDFS to generate FM radio (I) and (Q) signals for FM radio 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 two DDFS. The outputs of each DDFS may be a constant frequency while the inputs to each DDFS may vary in frequency.
