Part Number: TS3DV642
My customer asked us about differential impedance measurement by TDR for TS3DV642.As you can see, it is stable at around 104 Ω without TS3DV642, but it is around 117 Ω with TS3DV642.
Figure2: With TS3DV642
There is a difference with or without TS3DV642.
Is this an effect of ON resistance?The difference between presence and absence of TS3DV642 is 13 Ω.He is concerned that since the ON resistance of the TS3DV642 is TYP 6.5 Ω, since it matches when doubling it at the signal sink and source, the ON resistance is raised as it is.
Please let me know the above question.Also please let me know the solution to this symptom.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thank you for your reply.
My customer want to reduce the increased impedance.
Please let me know how to reduce the impedance.
