Description

rx_10g_frame_skip_err
[<n>-1:0]

Output

No

For the Interlaken protocol, asserted to indicate a

Skip Control Word error was received in a Skip

Control Word location within the metaframe.
This signal is sticky during the loss of block lock

and does not update until block lock is

re-established. This signal is pulse-stretched; you

must use a synchronizer.

rx_10g_frame_diag_
err[<n>-1:0]

Output

No

For the Interlaken protocol, asserted to indicate a

Diagnostic Control Word error was received in a

Diagnostic Control Word location within the

metaframe.
This signal is sticky during the loss of block lock

and does not update until block lock is

re-established. This signal is pulse-stretched; you

must use a synchronizer.

rx_10g_frame_diag_
status
[2<n>-1:0]

Output

No

For the Interlaken protocol, reflects the lane status

message contained in the framing layer Diagnostic

Word (bits[33:32]). This information is latched

when a valid Diagnostic Word is received in a

Diagnostic Word Metaframe location. This signal

is pulse-stretched; you must use a synchronizer.

Block Synchronizer

rx_10g_blk_lock
[<n>-1:0]

Output

No

Active-high status signal that is asserted when

block synchronizer acquires block lock. Valid for

the 10GBASE-R and Interlaken protocols, and any

basic mode that uses the lock state machine to

achieve and monitor block synchronization for

word alignment. Once the block synchronizer

acquires block lock, it takes at least 16 errors for

rx_10g_blk_lock

to be deasserted.

rx_10g_blk_sh_err
[<n>-1:0]

Output

No

Error status signal from block synchronizer

indicating an invalid synchronization header has

been received. Valid for the 10GBASE-R and

Interlaken protocols, and any legal basic mode that

uses the lock state machine to achieve and monitor

block synchronization for word alignment. Active

only after block lock is achieved. This signal is

generated by

rx_pma_clk

and is pulse-stretched by

3 clock cycles. You must use a synchronizer.
