TMUXHS4212: Schematic and layout review

Part Number: TMUXHS4212


Hi TIer

 Could you help me review the schematic and layout?

 The customer thinks their traces are crossing and not going well.

Thank you very much,

    Hi Yuxi,

    I see you are using this MUX in a type-C application. Can you share the layout as a .brd cadence file? I can't see the MUX connections from your image alone.

    I have another comment on the MUX SEL signal. It looks like you've routed CC1 directly from the type-C connector to this pin. This would be incorrect, as you need a CC controller to output a DIR signal for the MUX SEL pin.

    Do you have a CC controller in your design?

    Otherwise, the schematic connections look ok.

    Best,

    Shane

    Hi Yuxi,

    I hope you're doing well. Were you able to look at my questions from earlier?

    If you no longer need support, I can resolve this thread.

    Best,

    Shane
