Range
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.
On / Off Enables the rx_enh_data_valid port. This signal indicates when
RX data from RX FIFO is valid. This signal is synchronous to
rx_coreclkin.
On / Off Enables the rx_enh_fifo_full port. This signal indicates when
the RX FIFO is full. This is an asynchronous signal.
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.
On / Off Enables the rx_enh_fifo_empty port. This signal indicates when
the RX FIFO is empty. This signal is synchronous to
rx_coreclkin
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
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.
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
On / Off Enables the rx_enh_fifo_rd_en input port. This signal is
enabled to read a word from the RX FIFO. This signal is
synchronous to
On / Off Enables the rx_enh_fifo_align_val status output port. Only
used for Interlaken transceiver configuration rule. This signal is
synchronous to
On / Off Enables the rx_enh_fifo_align_clr input port. Only used for
Interlaken. This signal is synchronous to
Range
On / Off Enables the frame generator block of the Enhanced PCS.
5-8192 Specifies the metaframe length of the frame generator. This
metaframe length includes 4 framing control words created by the
frame generator.
On / Off Enables frame generator burst. This determines whether the
frame generator reads data from the TX FIFO based on the input
of port
