DS90UB928Q-Q1: Insertion loss failure in the FPD Link III interface IC DS90UB928Q-Q1.

Madhan Prasath T A

Part Number: DS90UB928Q-Q1

We are facing an issue that the insertion loss is failing for the FPD Link III IC (DS90UB928Q-Q1) during simulation in the CST tool. We have to fix this issue in the layout. We are requesting the TI to give suggestion for the improvement in layout.

Hi Madhan,

What serializer are you using in conjunction with 928 ?
What type of simulation are you running?
What channel spec recommendations are you following in this system?
What is your setup for this sim?
How long of a cable are you using?

Regards,
Fadi A.

Hi Fadi Abdulhameed,

Now we have seen some improvement in the insertion loss. We have one another query that is the RIN+ an RIN- pin have any internal protection diode to prevent from the over voltage.

Hi Madhan,

Yes they do. Also, here is the ESD ratings and recommended operation for all pins.
