I'm trying to measure FPD-Link signal quality of DS90UB948-Q1. However,I got a FPD-Link signal from RIN0/1± shown in picture below. It seem that it can not form one eye diagram or satisfy eye diagram test requirements.
So I have caught a eye diagram from CMLOUT± shown below.
According to the datasheet, output signal on CMLOUT± was recovered forward channel data from RIN±.
Then I wanna know if eye diagram on CMLOUT± can stand for FPD-Link signal quality totally？ Or is the any other way to measure signal quality from RIN± directly？
Thanks，
Best regards！
