Name Direction Description
tx_10g_diag_status
[2-1:0]
Input For the Interlaken protocol, provides diagnostic status
information reflecting the lane status message contained
in the Framing Layer Diagnostic Word (bits[33:32]). This
message is inserted into the next Diagnostic Word
generated by the Frame Generation Block. The message
must be held static for 5 cycles before and 5 cycles after
the tx_frame pulse. Synchronous to
tx_10g_clkout
.
tx_10g_burst_en
[-1:0]
Input For the Interlaken protocol, controls frame generator
reads from the TX FIFO. Latched once at the beginning
of each metaframe.When 0, the frame generator inserts
SKIPs. When 1, the frame generator reads data from the
TX FIFO. Must be held static for 5 cycles before and 5
cycles after the
tx_frame
pulse. Synchronous to
tx_10g_
clkout
.
tx_10g_frame
[-1:0]
Output For the Interlaken protocol, asserted to indicate the
beginning of a new metaframe inside the frame generator.
This signal is pulse-stretched; you must use a synchron‐
izer to synchronize with
tx_10g_clkout
.
Frame Synchronizer
rx_10g_frame
[-1:0]
Output For the Interlaken protocol, asserted to indicate the
beginning of a new metaframe inside the frame
synchronizer. This signal is pulse-stretched, you must use
a synchronizer. This signal is pulse-stretched; you must
use a synchronizer to synchronize with
rx_10g_clkout
.
rx_10g_frame_lock
[-1:0]
Output For the Interlaken protocol, asserted to indicate that the
frame synchronizer state machine has achieved frame
lock. This signal is pulse-stretched, you must use a
synchronizer. This signal is pulse-stretched; you must use
a synchronizer to synchronize with
rx_10g_clkout
.
Rx_10g_pyld_ins
[-1:0]
Output For the Interlaken protocol, asserted to indicate a SKIP
Word was not received by the frame synchronizer in a
SKIP Word location within the metaframe. This signal is
pulse-stretched, you must use a synchronizer. This signal
is pulse-stretched; you must use a synchronizer to
synchronize with
rx_10g_clkout
.
rx_10g_frame_mfrm_err
[-1:0]
Output For the Interlaken protocol, asserted to indicate an error
has occurred in the metaframe. This signal is
pulse-stretched, you must use a synchronizer to
synchronize with
rx_10g_clkout
.
