  • Method and system for encoding data for transmission over a serial link
    Patent number: 6628725
    Abstract: An exemplary embodiment of the invention is a method for encoding data into a 48B/50B format for transmission over a serial link. A data stream that includes characters is received and segmented into a six-character block. The block of six characters is translated into a 50-bit byte frame in 48B/50B format. A 48-bit word is created from the block of six characters by encoding the characters contained in the block. The 48-bit word is scrambled and a 2-bit synchronization sequence is appended to the scrambled 48-bit word. The result is the 50-bit byte frame in 48B/50B format. An alternate embodiment of the present invention includes a method for decoding data from the 48B/50B format.
