Altera 50G Interlaken MegaCore Function - Manual (Page 55)

Signal Name Direction Width (Bits) Description
burst_short_in
Input 4 Encodes the BurstShort parameter for the IP
core.
The 50G Interlaken IP core supports the
following valid value for this parameter:
1: 32 bytes
In general, the presence of the BurstMin
parameter makes the BurstShort parameter
obsolete.
burst_min_in
Input 4 Encodes the BurstMin parameter for the IP
core.
The IP core supports the following valid values
for this signal:
0: Disable optional enhanced scheduling. Altera
recommends you do not drive this value. If you
disable enhanced scheduling, performance is
non-optimal.
1: 32 bytes
2: 64 bytes
4: 128 bytes
The BurstMin parameter should have a value
that is less than or equal to half of the value of
the BurstMax parameter.
Altera recommends that you modify the value
of this input signal only when no traffic is
present on the TX user data interface. You do
not need to reset the IP core.
Real-Time Transmit Status Signals (Synchronous with tx_usr_clk)
tx_lanes_
aligned

ready to send traffic.
