JTAG SMT2 NC characteristic impedance

Question

A customer on our website asked the following question:

Regarding the JTAG-SMT2-NC:

Could you please let us know the characteristic impedance of the traces for TCK, TMS, TDI, and TDO? I saw in the datasheet that it should be below 100ohms, but we are crossing a back plane with the signals and would like to try to match our traces to yours as closely as possible.

The response is below.

Hello,

I have asked some of our applications engineers about this; they will get back to you here on the Forum.

Thanks,
JColvin

Hello,

The characteristic impedance is for long lines. The traces of the SMT2-NC are very short and the characteristic impedance is negligible. 

Best regards,

Bianca
