Available in configurations with 8B/10B
decoder.
A high level—the associated received code
group is a control (/Kx.y/) code group.
A low level—the associated received code
group is a data (/Dx.y/) code group.
The width of this signal depends on the
following channel width:
Available in configurations with 8B/10B
decoder.
A high level—a code group violation or
disparity error was detected on the
associated received code group. Use with
the rx_disperr signal to differentiate
between a code group violation and/or a
disparity error as follows:
