Parameter Range Description
Enable RX FIFO
alignment word
deletion
(Interlaken)
On / Off When you turn on this option, all alignment words (sync
words), including the first sync word, are removed after frame
synchronization is achieved. If you enable this option, you must
also enable control word deletion.
Enable RX FIFO
control word
deletion
(Interlaken)
On / Off When you turn on this option, Interlaken control word
removal is enabled. When the Enhanced PCS RX FIFO is
configured in Interlaken mode, enabling this option, removes
all control words after frame synchronization is achieved.
Enabling this option requires that you also enable alignment
word deletion.
Enable rx_enh_
data_valid port
On / Off Enables the rx_enh_data_valid port. This signal indicates
when RX data from RX FIFO is valid. This signal is synchro‐
nous to rx_coreclkin.
Enable rx_enh_
fifo_full port
On / Off Enables the rx_enh_fifo_full port. This signal indicates
when the RX FIFO has reached the specified full threshold. This
is an asynchronous signal.
Enable rx_enh_
fifo_pfull port
On / Off Enables the rx_enh_fifo_pfull port. This signal indicates
when the RX FIFO has reached the specified partially full
threshold. This is an asynchronous signal.
Enable rx_enh_
fifo_empty port
On / Off Enables the rx_enh_fifo_empty port. This signal indicates
when the RX FIFO has reached the specified empty threshold.
This signal is synchronous to rx_coreclkin.
Enable rx_enh_
fifo_pempty port
On / Off Enables the rx_enh_fifo_pempty port. This signal indicates
when the RX FIFO has reached the specified partially empty
threshold. This signal is synchronous to rx_coreclkin.
Enable rx_enh_
fifo_del port
(10GBASE-R)
On / Off Enables the optional rx_enh_fifo_del status output port. This
signal indicates when a word has been deleted from the rate
match FIFO. This signal is only used for 10GBASE-R
transceiver configuration rule. This is an asynchronous signal.
Enable rx_enh_
fifo_insert port
(10GBASE-R)
On / Off Enables the rx_enh_fifo_insert port. This signal indicates
when a word has been inserted into the rate match FIFO. This
signal is only used for 10GBASE-R transceiver configuration
rule. This signal is synchronous to rx_coreclkin.
Enable rx_enh_
fifo_rd_en port
(Interlaken)
On / Off Enables the rx_enh_fifo_rd_en input port. This signal is
enabled to read a word from the RX FIFO. It is only used for
Interlaken transceiver configuration rule. This signal is
synchronous to rx_coreclkin.
Enable rx_enh_
fifo_align_val
port (Interlaken)
On / Off Enables the rx_enh_fifo_align_val status output port. Only
used for Interlaken transceiver configuration rule. This signal is
synchronous to rx_clkout.
