HD3SS6126: schematic review of HD3SS6126 - Interface forum - Interface - TI E2E support forums

Jimmy:

       For two questions:

1. Do I need to connect it externally for SOC control? do you mean AC caps?

         2 An independent set of DC-DC 3.3V is used for HD3SS3220RNHR. There is no LED. Do I need to use 2A?

            I can't find HD3SS3220 in the updated schematic

Also  why CC1CC2 not connected for type-C connector?

For type-C, DP1/DP2 and Dm1/Dm2 are connected together at the connector

Hi Brian,

Thanks for your great support.

1. Do I need to connect it externally for SOC control? do you mean AC caps?

   It is not a coupling capacitor. Does the I2C of HD3SS3220RNHR need to be connected to the SOC? Or is it sufficient to reserve test points?

         2 An independent set of DC-DC 3.3V is used for HD3SS3220RNHR. There is no LED. Do I need to use 2A?

            I can't find HD3SS3220 in the updated schematic

Sorry, I have sent another schematic over E-mail, please help to review it. Thanks a lot.

Many Thanks,

Jimmy

For Q1: Do I need to connect it externally for SOC control?

  If I2C is needed, then you need to connect SCL/SDA to SOC .

Q2: I think you do need to use 2A.

Jimmy:

    for 3220_ID, ID needs to be pullup, so UR25 should be installed.

for TI_en_mux, it should be pull down, or controll by external signal.
