DS90UB954-Q1: about eye diagram

Part Number: DS90UB954-Q1
Other Parts Discussed in Thread: ALP

Hello，

 Do we have any application notes about how to test the eye diagram? For example, if the application is DS90UB953+DS90UB954, our customer hope to test the input FPD-link signal quality of DS90UB954, so could you have any instructions about testing eye diagram?

Best regards

Kailyn

    Hello Kailyn,

    We do not have such collateral since eye diagram is not one of the parameters we recommend to test for in the FPD-Link system (due to the fact that the channel is bidirectional). Instead we recommend to validate:

    - Transmission Channel high speed parameters such as Insertion Loss, Return Loss.

    - Margin Analysis Tool through ALP

    If you still want to measure eye-diagram, please refer to this Thread and this Thread.
