Parameter Range Description
teng_tx_framgen_burst_enable On/Off When you turn this option On, the
frame generator burst functionality is
enabled.
Enable tx_10g_frame port On/Off When you turn this option On, the 10G
PCS includes the tx_10g_frame output
port. When asserted, tx_10g_frame
indicates the beginning of a new
metaframe inside the frame generator.
Enable tx_10g_frame_diag_status port On/Off When you turn this option On, the 10G
PCS includes the tx_10g_frame_diag_
status 2-bit input port. This port
contains the lane Status Message from
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.
Enable tx_10g_frame_burst_en port On/Off When you turn this option On, the 10G
PCS includes the tx_10g_frame_burst_
en input port. This port controls frame
generator data reads from the TX FIFO.
The value of this signal is latched once at
the beginning of each Metaframe. It
controls whether data is read from the
TX FIFO or SKIP Words are inserted
for the current Metaframe. It must be
held static for 5 cycles before and 5
cycles after the tx_frame pulse. When
tx_10g_frame_burst_en is 0, the frame
generator does not read data from the
TX FIFO for current Metaframe. It
insert SKIPs. When tx_10g_frame_
burst_en is 1, the frame generator reads
data from the TX FIFO for current
Metaframe.
Interlaken Frame Synchronizer
The Interlaken frame synchronizer block achieves lock by looking for four synchronization words in
consecutive metaframes. After synchronization, the frame synchronizer monitors the scrambler word in
the metaframe and deasserts the lock signal after three consecutive mismatches and starts the synchroni‐
zation process again. Lock status is available to the FPGA fabric. The following table describes the
Interlaken frame synchronizer parameters.
