Abstract
A receiver for extracting binary data from a Manchester-encoded input signal. Sampling logic samples the input signal at a frequency greater than the bit cell rate to detect input edges. The sampling logic output is divided to provide a sampling clock having a frequency greater than the bit cell rate and which is synchronized with the input signal. The sampling clock is then utilized to sample the first bit cell half of the sampled input signal. The value obtained by sampling the first bit cell half is then inverted to provide extracted binary data.
