ABSTRACT:
An integrated circuit may enable transmission and reception of Bluetooth signals as well as FM signals. One or more clock signals may be generated via a phase-locked loop and may be utilized to enable Bluetooth transmission and reception. Bluetooth clock signals and frequency control words may be utilized by a direct digital frequency synthesizer to generate FM carrier signals that enable FM reception as well as digitally modulated signals for FM transmission. FM reception and transmission may be time division duplex. Frequency control words may be adjusted to compensate for variations in the Bluetooth clock signal frequency for FM carrier signals used in FM reception. Moreover, frequency control words may be adjusted to modulate a signal about the frequency of an FM carrier for transmission. Each of the Bluetooth clock signals, carrier signals and modulated signals comprise an in-phase component and a quadrature-phase component.
