Parameter Range Description
Enable rx_enh_
frame_lock port
On / Off Enables the rx_enh_frame_lock output port. When the
Interlaken frame synchronizer is enabled, this signal is asserted
to indicate that the frame synchronizer has acheived metaframe
delineation. This is an asynchronous output signal.
Enable rx_enh_
frame_diag_
status port
On / Off Enables the rx_enh_frame_diag_status output port. When
the Interlaken frame synchronizer is enabled, this signal
contains the value of the framing layer diagnostic word (bits
[33:32]). This is a 2 bit per lane output signal. It is latched when
a valid diagnostic word is received. This is an asynchronous
signal.
Table 2-15: Interlaken CRC32 Generator and Checker Parameters
Parameter Range Description
Enable
Interlaken TX
CRC-32
Generator
On / Off When you turn on this option, the TX Enhanced PCS datapath
enables the CRC32 generator function. CRC32 can be used as a
diagnostic tool. The CRC contains the entire metaframe
including the diagnostic word.
Enable
Interlaken TX
CRC-32
generator error
insertion
On / Off When you turn on this option, the error insertion of the
interlaken CRC-32 generator is enabled. Error insertion is
cycle-accurate. When this feature is enabled, the assertion of
tx_control[8] or tx_err_ins signal causes the CRC calcula‐
tion during that word is incorrectly inverted, and thus, the CRC
created for that metaframe is incorrect.
Enable
Interlaken RX
CRC-32 checker
On / Off Enables the CRC-32 checker function.
Enable rx_enh_
crc32_err port
On / Off When you turn on this option, the Enhanced PCS enables the
rx_enh_crc32_err port. This signal is asserted to indicate that
the CRC checker has found an error in the current metaframe.
This is an asynchronous signal.
Table 2-16: 10GBASE-R BER Checker Parameters
Parameter Range Description
Enable rx_enh_
highber port
(10GBASE-R)
On / Off Enables the rx_enh_highber port. For 10GBASE-R transceiver
configuration rule, this signal is asserted to indicate a bit error
rate higher than 10
-4
. Per the 10GBASE-R specification, this
occurs when there are at least 16 errors within 125 us. This is an
asynchronous signal.
