HI，as the title says, there is an option in GUI:
Do I neet to check the option "Relink o SYSREF"?
What does the "Relink o SYSREF" mean?
And what the use of "SYSREF for Startup", should I check it?
SYSREF for Startup : enable: require a SYSREF before CGS is output from serializer, Disable: Allow CGS to output beforeSYSREF occurs (recommended on framer to allow deframer CDR to lock and EQ to train)
Relink o SYSREF : Flag to indicate that a SYSREF is required to re-establish the link
Thank you for your reply!

you mean if JESD204B lost link when board is running , if I check this option, it can be re-linked by SYSREF. If I don't check it, it will not be re-link?
So this option should be checked, doesn't it?
By default the sysref on relink is disabled. If sysref on relink is enabled, then if the link is broken, then a sysref has to be given to re-establish the link. If disabled, then the link re-establishes by itself without requiring sysref.
