DS90C385A: DS90C385A : Insertion the damping resistor to TxCLKOUT+/TxCLKOUT-

Hello,

We will look into this and get back to you.

Hello,

Why do they need to add damping resistors on TxCLKOUT? What are they trying to achieve? Can you please share a block diagram of the system?

Dear Yaser-san,

Thank you for your cooperation.

Sorry for delayed reply. Finally I got customer's reply.

  > Why do they need to add damping resistors on TxCLKOUT? What are they trying to achieve?

     As background of this question,  customer suspects taht the LVDS signal may be the source of the radiation noise.

     Customer thinks that adding the damping resistance would reduce the radiation noise by making the rise and fall of the differential clock waveform of the LVDS signal gentler.

  > Can you please share a block diagram of the system?

  Customer thinks to do it. I think it is difficult.

I appreciate your quick reply.

Best regards,
