Scramble of payload and preamble in 10SPE with synchronous and self-synchronous scrambling

Abstract:

An apparatus includes an encoder circuit and a scrambler circuit configured to receive a frame, the frame including a preamble and a payload. The scrambler circuit is further configured to scramble contents of the frame including the payload and at least a portion of the preamble, provide synchronization information with results of scrambling the contents, and send results of scrambling the contents to the encoder circuit.
