Method and apparatus for providing data stream for cost effective transmission links

摘要

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 +E,fra 4/5+EE 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.
