Name Direction Clock Description
de-skewed. A value of 1 indicates all lanes
are aligned and de-skewed. When this
signal is a 1, the RX path is aligned and can
receive packet data.
stat_rx_aligned_err Output clk
Loss of Lane Alignment/De-Skew. This
signal indicates an error occurred during
lane alignment or lane alignment was lost.
A value of 1 indicates an error occurred.
stat_rx_crc24_err Output clk
Control Word CRC24 Error. This signal
indicates whether a mismatch occurred
between the received and the expected
CRC24 value. A value of 1 indicates a
mismatch occurred.
stat_rx_overflow_er
r
Output clk
RX FIFO Overflow Error. This signal
indicates if the LBUS interface is being
clocked too slowly to properly receive the
data being transmitted across the link. A
value of 1 indicates an error occurred.
In normal operation, this signal will
always be sampled as 0. If this signal is
sampled as 1, the clocks are not set to
proper frequencies and must be fixed.
stat_rx_mf_err[11:0] Output clk
Meta Frame Synchronization Word Error.
These signals indicate that an incorrectly
formed Meta Frame Synchronization Word
was detected in the respective lane. A value
of 1 indicates an error occurred.
stat_rx_framing_err
[11:0]
Output clk
Framing Error. These signals indicate that
an illegal framing pattern was detected in
the respective lane. A value of 1 indicates
an error occurred.
stat_rx_msop_err Output clk
Missing Start-of-Packet (SOP) Error. This
signal indicates that a Missing Start-of-
Packet was detected (and corrected).
stat_rx_meop_err Output clk
Missing End-of-Packet (EOP) Error. This
signal indicates that a Missing End-of-
Packet was detected (and corrected).
stat_rx_burst_err Output clk
This signal indicates that a BurstShort or a
burst length error was detected.
stat_rx_misaligned Output clk
Alignment Error. This signal indicates that
the lane aligner did not receive the
