ABSTRACT:
A physical layer device includes a converter module to convert input data having a first predetermined number of bits into output data having a second predetermined number of bits. A scrambler module is operable to be activated and deactivated. The scrambler module receives the output data having the second predetermined number of bits. An encoding module modulates the output of the scrambler module in accordance with one of a plurality of modulation types and generates an encoded output signal having an output level. The encoding module is operable to vary the output levels of the encoded output signal.
