Abstract
A data capture circuit includes a character detection circuit and a word detection circuit. The character detection circuit determines values for characters represented by a signal having a frequency. In making such determinations, the values for characters are based on an accumulation of differential samples of the signal. The word detection circuit is coupled to receive the values for characters from the character detection circuit. The word detection circuit determines a word value based on the received values for characters. The word detection circuit includes a comparison circuit and an accumulator. The comparison circuit compares a value for a character in a word to a to a value for at least one other character in the word and provides a character value based on the comparison. The accumulator has an input coupled to receive character values from the comparison circuit and an output to provide a summation of character values received by the accumulator.
