Abstract
Aspects of a method and system for transmission or reception of signals utilizing a DDFS clocked are provided. A first oscillator signal utilized for transmission and/or reception of signals of a first wireless communication protocol may be generated, and a direct digital frequency synthesizer (DDFS) may be clocked by the first oscillator signal to generate one or more second oscillator signals. The one or more second oscillator signals may be modulated to generate a signal adhering to a second wireless communication protocol. The one or more second oscillator signals may be utilized to demodulate signals of the second wireless communication protocol. A control word input to the DDFS may control a frequency of the one or more second oscillator signals generated by the DDFS. Simultaneous transmission and reception of signals of the second wireless communication protocol may be simulated by switching the control word input to the DDFS between two values.
