Hi Team,

My customer is looking Mux device for XFI interface. TMUXHS4212 seems to be usable such the use case though, do you have any concerns to use TMUXHS4212 as XFI Mux?

Hi Brian-san,

I'm not sure so I'm asking. It looks 850mVp-p in the following document. Data rate should be 10.3125Gbps, NRZ so device need to have 5G band wide as min, 5 times wider band wide should be perfect in my understanding.

Could you double check that?

Regards,

Takashi Onawa
