Abstract:
A method and system for wireless communication using integrated clock generation for Bluetooth and FM transmit and FM receive functions may include generating a clock signal to enable transmission and/or reception of Bluetooth signals; and clocking a Direct Digital Frequency Synthesizer (DDFS) via the generated clock signal to generate one or more signals by the DDFS that enable transmission or reception of FM signals. The generated clock signals for the Bluetooth and for the FM transmit and receive functions may include an in phase and quadrature phase component. Time Division Duplex of FM transmission and reception and simultaneous FM transmission and FM reception may be simulated by switching the control frequency word at a certain rate. The DDFS may also receive control words to compensate for frequency changes in the Bluetooth LO. The FM signals reception and transmission may be controlled by a bi-directional coupler.
