Chapter 6

Transceiver Verification

his chapter describes how to verify the FPGA transceivers via the QSFP28 connector. A

40Gbps loopback test code called

alt_e40

which is available in the System CD. The source

code is also available in the in the system CD.

6.1

Transceiver Test Code

The transceiver test code is used to verify the transceiver channels via the QSPF28 ports through

an external loopback method. The transceiver channels are verified with the data rates 10.3125

Gbps for the FPGA with PRBS31 test pattern.

6.2

QSFP28 Ports

To enable an external loopback of the transceiver channels, QSFP28 loopback fixtures, as shown in

Figure 6-1

, are required. The fixture is available at:

https://multilaneinc.com/product/ml4002-28/

Figure 6-1

QSFP28 Loopback fixtures

Figure 6-2

shows the FPGA board with four QSFP28 loopback fixtures installed.
