Circuits of coder/decoder and error detection in 5B6B transmission code

This paper presents circuits for transforming an electrical signal in the form of a sequence of binary digits into a form having lower disparity, wherein successive groups of five binary digits in the sequence are coded as groups of six binary digits. The coding is arranged according to the specific code translation map. The paper also includes circuits for decoding the groups of digits so produced according to the decoding translation map. A description of a violation detector and a violation rate measurement is also given
