Hi Jeff,

Please allow me some time to review the schematic. I will aim to respond by Monday next week (1/26).

I took a quick glance at the schematic, it seems like you are not using the Mux/Demux feature of the SN75LVPE5421/SN75LVPE5422. Perhaps DS320PR410 may simplify your design. DS320PR410 is TI's 4 channel redriver without Mux/Dmux feature.

Thanks and Regards,

Charles W

Hi Charles,

We need co-use with other project so choose the SN75LVPE5421/SN75LVPE5422.

In this application, also use DS320PR410 * 4pcs, right? thanks!

Hi Charles,

I found the SN75LVPE5421/SN75LVPE5422. price seems close to DS320PR410.

It seems only save the board space if we change to DS320PR410, right? thanks!
