Part Number: HD3SS3212
Other Parts Discussed in Thread: TMUXHS4212

Hi Team,

Customer  will used the HD3SS3212 in the PC project. They had completed the schematic. Would you please help me to check it?

Thanks a lot

  • Hi, 

    Some comment below:

    • I recommend customer to use our latest TMUXHS4212
    • If this device is connected to a USB-C connector then TX1/2 should be AC coupled with 220nF and RX1/2 should be AC coupled with 330 nF. These values are highly recommended when AC coupling to a USB-C connector.
      • If AC coupled at teh connector then AC coupling on A0 and A1 is not needed
    • Is OE being controlled?
    • Is PD/CC controller controlling the SEL pin?
