DS90UB948-Q1: RIN polarity inversion

Part Number: DS90UB948-Q1

Tool/software:

Hello,

Maybe is a silly question, but we'd like to confirm it.

There is no way to invert the polarity of DS90Ux948 RIN inputs (e.g. from RIN1P to RIN1N and so on) by configuration registers, correct?

This would be to fit together different designs.

Same question for serializer DS90Ux947.

Regards,

Luca

  • Hi Luca,

    Question: There is no way to invert the polarity of DS90Ux948 RIN inputs (e.g. from RIN1P to RIN1N and so on) by configuration registers, correct?

    Answer: You are correct as there is no way to invert the polarity of the RIN1 pins by configuration registers so you would need to fit your designs around that. 

    Question: Same question for serializer DS90Ux947

    Answer: For the DS90Ux947, I am assuming you are talking about the Dout1 and Dout0 pins and the same applies for these pins as well as their polarity cannot be reconfigured through registers

    Best,
