Description
tx_10g_data_valid
[<n>-1:0]
Input Yes
When asserted, indicates if tx_data is valid Use of
this signal depends upon the protocol you are
implementing, as follows:
10G BASE-R: Tie to 1'b1
Interlaken: Acts as control for FIFO write
enable. You should tie this signal to tx_10g_
fifo_pempty.
Basic with phase compensation FIFO: Tie to
1'b1 as long as tx_coreclkin = data_rate/
pld_pcs interface width. Otherwise, tie this
signal to tx_10g_fifo_pempty.
Basic with phase compensation FIFO in register
mode. This mode only allows a 1:1 gear box
ratio such as 32:32 and 64:64; consequently,
you can tie tx_10g_data_valid to 1’b1.
tx_10g_fifo_full
[<n>-1:0]
Output Yes When asserted, indicates that the TX FIFO is full.
Synchronous to tx_std_clkout,
tx_10g_fifo_pfull
[<n>-1:0]
Output Yes When asserted, indicates that the TX FIFO is
partially full.
tx_10g_fifo_empty
[<n>-1:0]
Output No TX FIFO empty flag. Synchronous to tx_std_
clkout. This signal is pulse-stretched; you must
use a synchronizer.
tx_10g_fifo_pempty
[<n>-1:0]
Output No TX FIFO partially empty flag. Synchronous to tx_
std_clkout. This signal is pulse-stretched; you
must use a synchronizer.
tx_10g_fifo_del
[<n>-1:0]
Output Yes When asserted, indicates that a word has been
deleted from the rate match FIFO. This signal is
used for the 10GBASE-R protocol.
tx_10g_fifo_insert
[<n>-1:0]
Output No When asserted, indicates that a word has been
inserted into the rate match FIFO. This signal is
used for the 10GBASE-R protocol. This signal is
pulse-stretched, you must use a synchronizer.
