HD3SS3411: Should I place AC couple caps?

Hardy Xue

Part Number: HD3SS3411

Hi Team,

My customer is designing a PCIE mux based on our HD3SS3411. When it is applied on PCIE clock, do AC couple caps need to be placed on TX pair?

Could I suggest customer to follow datasheet to place AC cap?

Best regards,

Hardy

you are talking about clock channel or TX?

Hi Brain,

Due to I am not similar about it, please help to correct if there are any mistake I said.

In my opinion, we can use mux for clock cannel or TX. We can follow suggestion of datasheet to place AC caps for TX application.

For PCEI clock application, we don't need to place AC caps on differential pair. Is it correct?

Best regards,

Hardy

Just place cap on TX, no Cap on PCie clk signal
