A method and system for a frequency shift key demodulation is provided. The system includes a counting block for counting a reference clock within a window defined by a modulated signal, a detector for comparing a count value output from the counting block with digital multi-level thresholds and outputting baseband data based on the comparison, and a configurations block for configuring at least one of the counting block and the detector. The method includes counting a reference clock within a window defined by the FSK modulated signal and outputting a count value as a result of the counting, and comparing the count value with multi-level thresholds to output baseband data based on the comparison.
