Part Number: TMUX1574

Tool/software:

Dear Ti

Is the TMUX1574 suited for differential signals like SGMII ?

From the datasheet it seems to be only applicable to single-ended applications?

Regards

A differential signal needs two channels. This will work (if the switch supports the required voltages and bandwidth).

Hi Clemens

Is the skew between the channels low enough to produce a good eye opening for a differential signal at the maximum bandwidth of 2GHz supported by the device?

I guess 18 ps is low enough (see section 6.7).
