A method for jam setting an initial frequency of a data clock recovery loop according to one embodiment includes generating a frequency error signal in a frequency error detector from sideband signals within a backscattered radio frequency signal, wherein the frequency error accumulates in a frequency error filter coupled to an output of the frequency error detector; at about an end of an acquisition period, freezing the accumulated frequency error in the frequency error filter; and using the frozen accumulated frequency error to jam set an initial frequency of a data clock recovery loop. Such methodology may also be implemented as a system using logic for performing the various operations. Additional systems and methods are also presented.
