DS110RT410: Provide Bias to HD3SS3412 Multiplexer

Nicolas Striebig

Part Number: DS110RT410

Hi,

Is it possible to DC-couple a HD3SS3414 Multiplexer to a DS110RT410 Retimer to bias the Multiplexer (as shown in the picture), if the Mux inputs and the Retimers output are AC-coupled?

Thanks,

Nicolas

Hi Nicolas,

I would not use this approach. The DS110RT410 Rx common mode is 2.5V. This is above the HD3SS341x common mode specification. I would look at using the transmit common mode voltage to bias the HD3SS341x mux in this case.

Regards,

Lee
