Viewing GTH Transceiver Operation
After completing
configured and running. The status and test settings are displayed on the serial I/O link tab
in the Links window shown in
Review the line rate and RX bit error count. The line rate for all four GTH transceivers is
12.5 Gb/s (see Status in
X-Ref Target - Figure 1-19
In Case of RX Bit Errors
If there are initial bit errors after linking, or as a result of changing the TX or RX pattern, click
the respective BERT Reset button to zero the count.
If the Status column shows No Link for one or more transceivers:
• Make sure the blue elastomer seal is connected to the bottom of the Bulls Eye cable
(refer to
Figure
• Increase the TX differential swing of the transceiver (to compensate for any loss due to
PCB process variation).
• Click the respective TX Reset button followed by BERT Reset.
