Chapter 7
Transceiver Verification
his chapter describes how to verify the FPGA transceivers for the QSFP+ by
using the test code provided in the TR10a-LPQ system CD.
7.1
Function of the Transceiver Test Code
The transceiver test code is used to verify the transceiver channels for the QSPF+ ports
through an external loopback method. The transceiver channels are verified with the
data rates 10.3125 Gbps with PRBS31 test pattern.
7.2
Loopback Fixture
To enable an external loopback of transceiver channels, one of the following two fixtures
are required:
