Parameter Range Description
Enable RX data
bitslip
On / Off When you turn on this option, the Enhanced PCS RX block
synchronizer operates in bitslip mode. When enabled, the rx_
bitslip port is asserted on the rising edge to ensure that RX
parallel data from the PMA slips by one bit before passing to the
PCS.
Enable RX data
polarity
inversion
On / Off When you turn on this option, the polarity of the RX data is
inverted. This allows you to correct incorrect placement and
routing on the PCB.
Enable tx_enh_
bitslip port
On / Off Enables the tx_enh_bitslip port. When TX bit slip is enabled,
this signal controls the number of bits by which the TX parallel
data slips before going to the PMA.
Enable rx_bitslip
port
On / Off Enables the rx_bitslip port. When RX bit slip is enabled, the
rx_bitslip port is asserted on the rising edge to ensure that
RX parallel data from the PMA slips by one bit before passing
to the PCS. This port is shared between Standard PCS and
Enhanced PCS.
Table 2-22: KR-FEC Parameters
Parameter Range Description
Enable RX KR-
FEC error
marking
On/Off When you turn on this option, the decoder asserts both sync
bits (2'b11) when it detects an uncorrectable error. This feature
increases the latency through the KR-FEC decoder.
Error marking
type
On/Off Specifies the error marking type (10G or 40G).
Enable KR-FEC
TX error
insertion
On/Off Enables the error insertion feature of the KR-FEC encoder. This
feature allows you to insert errors by corrupting data starting a
bit 0 of the current word.
KR-FEC TX
error insertion
spacing
User Input (1 bit to
15 bit)
Specifies the spacing of the KR-FEC TX error insertion.
Enable tx_enh_
frame port
On/Off
Enables the tx_enh_frame port.
Enable rx_enh_
frame port
On/Off Enables the rx_enh_frame port.
Enable rx_enh_
frame_diag_
status port
On/Off Eables the rx_enh_frame_diag_status port.
