rx_10g_fifo_pfull[<n>-1:0]
Output No
RX FIFO partially full flag.Synchronous to
rx_10g_clkout
. This signal is pulse-stretched; you
must use a synchronizer.
rx_10g_fifo_empty[<n>-1:0]
Output Yes Active high RX FIFO empty flag,
rx_10g_fifo_pempty
[<n>-1:0]
Output Yes Active high. RX FIFO partially empty flag,
rx_10g_fifo_align_clr
[<n>-1:0]
Input Yes
For the Interlaken protocol, this signal clears the current
word alignment when the RX FIFO acts as a deskew
FIFO. When it is asserted, the RX FIFO is reset and
searches for a new alignment pattern.
rx_10g_fifo_align_en
[<n>-1:0]
Input Yes
For the Interlaken protocol, you must assert this signal
to enable the RX FIFO for alignment.
rx_10g_align_val[<n>-1:0]
Output Yes
For the Interlaken protocol, an active high indication
that the alignment pattern has been found
Rx_10g_fifo_del[<n>-1:0]
Output No
When asserted, indicates that a word has been deleted
from the TX FIFO. This signal is used for the
10GBASE-R protocol. This signal is pulse-stretched;
you must use a synchronizer.
Rx_10g_fifo_insert
[<n>-1:0]
Output Yes
Active-high 10G BaseR RX FIFO insertion flag
When asserted, indicates that a word has been inserted
into the TX FIFO. This signal is used for the 10GBASE-R
protocol.
CRC32
rx_10g_crc32err[<n>-1:0]
Output No
For the Interlaken protocol, asserted to indicate that the
CRC32 Checker has found a CRC32 error in the current
metaframe. Is is asserted at the end of current
metaframe. This signal is pulse-stretched; you must
use a synchronizer.
Frame Generator
tx_10g_diag_status
[2<n>-1:0]
Input No
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.
tx_10g_burst_en[<n>-1:0]
Input No
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.
