A method and apparatus for frequency shift-keying (FSK) demodulation includes processing that begins by generating a charge signal, a data acquisition signal, and a reset signal from an I component and a Q component of an FSK modulated signal. The processing continues by generating a delta frequency signal based on the charge signal, the data acquisition signal, and the reset signal. The delta frequency signal is representative of the frequency difference used within the FSK modulation to indicate a logic 1 and a logic 0. The processing then continues by demodulating the delta frequency signal to recapture a stream of data.
