Figure 2–21. 8B/10B Decoder
The 8B/10B decoder in single-width mode translates the 10-bit encoded
data into the 8-bit equivalent data or control code. The 10-bit code
received must be from the supported Dx.y or Kx.y list with the proper
disparity or error flags asserted. All 8B/10B control signals, such as
disparity error or control detect, are pipelined with the data and
edge-aligned with the data.
decoded in the 8-bit data + 1-bit control indicator.
Figure 2–22. 8B/10B Decoder Conversion
The 8B/10B decoder in double-width mode translates the 20-bit
(2 × 10-bits) encoded code into the 16-bit (2 × 8-bits) equivalent data or
control code. The 20-bit upper and lower symbols received must be from
the supported Dx.y or Kx.y list with the proper disparity or error flags
