This page can assist the user in tuning the CTLE settings to best match their system. Use it to display the eye height of the signal passing through the redriver, for all 20 CTLE index settings. Select the channel you would like to test, and click the Sweep CTLE button. The redriver will automatically detect the eye height with each index setting and display it in the plot below.
Note that this plot displays the eye heights directly at the output pins of the redriver. It is recommended to also use other lane margining tools to monitor signal quality at each end of the link. This tool should only be used as a reference and cannot guarantee optimal system performance based on this plot alone.
