6 System Page

This page allows users to estimate optimal CTLE settings for their application, based on known pre and post channel losses. This feature is also available in Demo Mode.

1. Enter the known Pre and Post-channel losses into each of the boxes. The GUI will show whether the losses are within the limit of the redriver or not.
   
2. Click the calculator button next to the transmission lines to calculate loss for PCB traces. Enter the trace material, width, length, and so on, and then click the Apply button.
   
3. The table will highlight suggested CTLE values for each PCIe Tx Preset, based on the losses you entered. You can use the lowest part of the screen to apply these CTLE settings, or do it from the high-level page. Note that these are only estimated values and are not guaranteed to be the best settings. Further IBIS model simulation, or bit error rate testing can be used to further determine the optimal redriver settings.
