Hi,

There is a GUI which can help you understand the DS100DF410 equalization settings and draw an eye diagram of the received eye. You will need access to the devices SMBus port. Here is a link to the webpage which has the Sigcon Architect tool free to download.

Hi,

I most cases using the default adapt mode and standard CTLE table allows the DS100DF410 to achieve a robust eye opening. In order to help fix the eye we need to understand the current eye diagram, the DS100DF410 CTLE/DFE settings, and the channel on the input side of the retimer.

The best way to get all the device settings is to dump (read) all of the channel registers into a text file so we can look closely at the device configuration and settings.

Lee
