Abstract: The disclosure relates to a coding module for an Ethernet transceiver. The coding module may include circuitry configured to: receive data-signaling representative of one or more data words; encode the data-signaling into one or more DC-balanced words each having a DC-balanced-word-length; provide a prepended-word for a first transmission, where a length of the prepended-word is at least as long as the DC-balanced-word-length; and provide the one or more DC-balanced words for a second transmission, where the second transmission is subsequent to the first transmission. The coding module may include circuitry configured to: receive a prepended-word and provide a logic-high signal to an Energy Detect terminal; receive one or more DC-balanced words each having a DC-balanced-word-length; remove a DC-balanced coding from the one or more DC-balanced words to generate data signaling representative of one or more data words; and provide the data signaling to an output terminal.

Abstract: An apparatus comprising an encoder is configured to: detect a first edge in the input signal and, in response, provide a pulse generation sequence comprising the encoder being configured to: generate, in the output signal, a first pulse, wherein the first pulse is provided over first and second minimum time periods irrespective of an edge subsequent the first edge being present in the input signal; and obtain a first sample of the input signal; and obtain a second sample at an end of the first pulse; and if the first sample and the second sample are indicative of different voltage levels, generate a second pulse; or if the first and second sample and the same maintain the voltage level in the output signal.
