ABSTRACT:
A circuit for decoding a high speed Manchester encoded digital communication signal is provided. The circuit includes a pair of latch circuits which are used to detect clock edges in the encoded signal for providing respectively set and reset pulses to a third latch circuit, an output of which comprises the decoded data of the Manchester code signal. Additional logic is provided to extract a clock signal from the Manchester code signal.
