Abstract
The system and method encodes a binary sequence of data bits into a sequence of ternary symbols and transmits the sequence of ternary symbols over a communication link. The encoding is performed so that no two consecutive symbols of the sequence are alike. The system and method assume that, for encoding, the previously encoded non-null symbol and the previously encoded symbol must be stored in a memory system. The sequence of symbols is transmitted in lieu of the binary sequence of data bits and decoded by a receiving device in order to restore the binary sequence of data bits from the received sequence of symbols. The decoding procedure assumes that three symbols must be received before a bit can be recovered. Hence, the system and method allow a self-delineation or self-sampling of a very-high speed data communication interface that is insensitive to large timing variations and skews.
