Patent ID: 6954491

Claim:
A high speed digital transmitter capable of sending side channel data, the transmitting comprising: a channel zero encoder having first and second inputs and an output, the first input receiving channel zero primary data, the second input receiving a channel zero DE out signal, and the output producing channel zero encoded data, the channel zero encoder operative to produce channel zero encoded data based at least in part on the channel zero primary data and the channel zero DE out signal; a channel one multiplexer having at least first and second data inputs, at least one control input, and at least one output, the channel one multiplexer operative to multiplex channel one primary data and channel one side channel data, the first data input receiving channel one primary data, the control input receiving a DEI signal, and the output providing a multiplexed signal including channel one side channel data and channel one primary data; a channel one DE out control logic having a first input and an output, the channel one DE out control logic operative to produce a channel one DE out signal for facilitating transfer of channel one side channel data, the first input receiving a DEI signal, and the output producing a channel one DE out signal; and a channel one encoder having first and second inputs and an output, the first input receiving the output of the channel one multiplexer, the second input receiving the output of the channel one DE out control logic, the output producing channel one encoded data, the channel one encoder operative to produce channel one encoded data based at least in part on the first and second inputs.
