ABSTRACT:
Aspects of a method and system for simultaneous transmission and reception of FM signals utilizing a DDFS clocked by an RFID PLL are provided. In this regard, a plurality of signals utilized to transmit or receive FM communication may be generated by clocking a plurality of DDFSs via a signal generated to enable RFID communication. The DDFSs may be controlled via one or more control words, which may be generated by a processor. In this regard, the control words may determine a frequency and/or phase of the signals output by the DDFSs. The control words may be adjusted to maintain a constant phase and/or frequency at the DDFS outputs in spite of changes to the signal clocking the DDFS. Accordingly, signals of two or more frequencies may be generated by the DDFSs to allow simultaneous transmission and reception of FM signals.
