Abstract
A system and method for encoding and decoding binary data for serial transmission over a physical medium provides a highly efficient and less complex coding scheme while guaranteeing clocking information and guaranteeing an NRZ(I)-disparity of no greater than one per five-bit word. The system and method of the present invention comprise a 4/5 encoder which enables each nibble to be encoded and decoded independently from one another. The Coding system and method of the present invention guarantees an NRZ(I)-disparity having a magnitude of no greater than one for any word after NRZ(I) while providing at least one word with 'NRZ(I) comma' property.
