Abstract: The present invention provides a system and method for using a single digzed component of an analog signal to be converted into a pair of digital signals used to re-establish the analog signal. A low level serial transceiver transforms a first analog signal into a first digital signal representing the complement of the first analog signal. The first digital signal is propagated through an electronic interface circuit such as a matrix switch or through some electronic circuit used to detect characteristics of the analog signal. In response to receiving the first digital signal, a logic circuit generates a second digital signal representing the analog signal, and also outputs the first digital signal. In response to receiving the first and second digital signals, a retimer generates a third digital signal comprising a series of pulses.

Abstract: An apparatus is disclosed for retiming and decoding Manchester-encoded data o produce a locally-formatted waveform, and for encoding a locally-formatted waveform in a Manchester-encoded format. The apparatus includes an all-digital retimer which retimes the Manchester-encoded waveform while monitoring the waveform to detect the presence of a data frame therein. The retimer detects the data frame by identifying a synch bit which initiates a frame and detecting when a maximum intra-frame signaling distance has been exceeded. A decoder receives the retimed waveform, together with an envelope signal defining the data frame and decodes the retimed waveform into a locally-coded format. The encoder receives a locally-formatted signal together with a signal defining a data frame and encodes the locally-formatted signal into a framed Manchester-encoded signal.
