ABSTRACT:
A high speed, two-way serial interface with a scrambler and de-scrambler may be tested by sending a single word repeatedly through the scrambler to create a pseudo-random sequence. The pseudo-random sequence is then passed through the transmitter and looped back through the receiver of the serial interface. The pseudo-random sequence is then descrambled and compared to the input word. Since the input sequence is only a single word rather than a series of words, the comparison is very simple and capable of being performed within the serial interface itself without the need for external test equipment.
