Abstract
A method and apparatus for a state-driven decoder for decoding a Manchester encoded signal. The decoder comprises an input sampling stage, an over-sampling clock, and a digital logic state machine. The over-sampling clock operates at a frequency which is less than five times the data rate of the encoded signal. The input sampling stage asynchronously samples the encoded signal at the frequency of the over-sampling clock and a produces a stream of pulse samples. The digital logic state machine analyzes the stream of pulse samples in groups and based on the logic levels of each group of pulse samples generates an output bit corresponding to the decoded Manchester signal.
