8B/10B Encoder
The 8B/10B encoder generates 10-bit code groups from the 8-bit data and 1-bit control
identifier. The 8B/10B encoder operates in two modes: single-width and
double-width.
double-width mode.
The left side of
mode, the 8B/10B encoder translates the 8-bit data to a 10-bit code group (control
word or data word) with proper disparity. If the control_code input is high, the
8B/10B encoder translates the input data[7:0] to a 10-bit control word. If the
control_code input is low, the 8B/10B encoder translates the input data[7:0] to a
10-bit data word.
You can use the tx_forcedisp and tx_dispval ports to control the running disparity
of the generated output data. For more information, refer to
