摘要：
In systems and methods for randomizing data communicated across a digital interface, a PN sequence is applied to a series of shift registers (141). An array of exclusive-or gates (142) is provided to scramble each bit of the current data word using a respective output of one or several of the shift registers. A second pseudonoise sequence is additionally applied in parallel to another array of exclusive-or gates (143). Additional lines are provided to communicate the PN sequences from the transmitting side to the receiver side. Also, corresponding arrays of exclusive-or gates (152, 153) and shift-registers (151) coupled to the PN sequence lines are disposed on the receiver side to recover the original data using the PN sequences.
