DS90UB941AS-Q1: DS90UB941AS-Q1 Port0 Output P/N Swap

Hi Gil,

We found an interesting phenomenon on the customer side.

The customer's DOUT+ and DOUT- are connected in reverse, and the result can work normally, but DOUT+ and DOUT- are connected according to the correct cable sequence, but it doesn't work.

So we want to confirm, if it is not a hardware connection problem, is it possible that the DSI signal output by the SOC is wrong?

Is there a way to adjust the DSI signals output by the SOC into the correct order?

Thanks

Xiaoxiang

Can you clarify what you mean by correct cable sequence?

Please share additional information:

1. Can you share the schematic?
