Description

irx_err Output 1

Indicates an errored packet. This signal is valid only when both

irx_num_valid[2:0] and irx_eopbits[3:0] are non-zero. When a

CRC24 or other error occurs, the 50G Interlaken IP core asserts this

signal for all open channel packets to label them all as errored packets,

because the IP core cannot assign the error to a specific channel.

Signal Name Direction Width (Bits) Description

SERDES Pins

rx_pin Input Number of lanes Receiver SERDES data pin on the RX Interlaken

link.

tx_pin Output Number of lanes Transmit SERDES data pin on the TX

Interlaken link.

TX Burst Control Settings

burst_max_in Input 4 Encodes the BurstMax parameter for the IP

core. The actual value of the BurstMax

parameter must be a multiple of 64 bytes. While

traffic is present, this input signal should

remain static. However, when no traffic is

present, you can modify the value of the burst_

max_in signal to modify the BurstMax value of

the IP core.

The 50G InterlakenIP core supports the

following valid values for this signal:

2: 128 bytes

4: 256 bytes
