Some representative embodiments are directed to systems and methods for randomizing data communicated across a digital interface. In some representative embodiments, a PN sequence is applied to a series of shift registers. An array of exclusive-or gates is provided to scramble each bit of the current data word using a respective output of one or several of the shift registers. In some embodiments, a second pseudo-noise sequence is additionally applied in parallel to another array of exclusive-or gates. Additional lines are provided to communicate the PN sequences from the transmitting side to the receiver side. Also, corresponding arrays of exclusive-or gates and shift-registers coupled to the PN sequence lines are disposed on the receiver side to recover the original data using the PN sequences.
