Description
Enable rx_10g_fifo_rd_en port
(Interlaken)
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_fifo_rd_en
input port. Asserting this signal reads a
word from the RX FIFO. This signal is
only available for the Interlaken
protocol.
Enable rx_10g_fifo_align_val port
(Interlaken)
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_fifo_align_
val
output port. This signal is asserted
when the word alignment pattern is
found. This signal is only available for
the Interlaken protocol.
enable rx10g_clk33out port
On/Off
When you turn this option On, the 10G
PCS includes a divide by 33 clock output
port. You typically need this option
when the fabric to PCS interface width
is 66.
Enable rx_10g_fifo_align_clr port
(Interlaken)
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_fifo_align_
clr
input port. When this signal is
asserted, the FIFO resets and begins
searching for a new alignment pattern.
This signal is only available for the
Interlaken protocol.
Enable rx_10g_fifo_align_en port
(Interlaken)
On/Off
When you turn this option On, the 10G
PCS includes the
rx_10g_fifo_align_
en
input port. This signal is used for
FIFO deskew for Interlaken. When
asserted, the corresponding channel is
enabled for alignment. This signal is
only available for the Interlaken
protocol.
Interlaken Frame Generator
TX Frame generator generates the metaframe. It encapsulates the payload from MAC with the framing
layer control words, including sync, scrambler, skip and diagnostic words. The following table describes
the Interlaken frame generator parameters.

frame generator block of the 10G PCS is
enabled.
teng_tx_framgen_user_length
0-8192
Specifies the metaframe length.
