HD3SS6126: schematic review of HD3SS6126

Jimmy Lai

Part Number: HD3SS6126

Dear Team,

1.The schematic has been drawn. Regarding HD3SS6126, we will convert USB 3.0 Type-A to USB Typc-C interface. Can you help review it to see if it meets the design requirements?

2. We plan to use the 5G NR LTE Dongle with USB Type-C interface, which does not require PD control, Micro USB ID, or LED functions;
Could you please tell me how to set SEL_0, SEL_1, HS_OE0# and HS_OE1# so that they can supply two channels at the same time?

Many Thanks,

Jimmy

    Jimmy:

            0.33uf cap is recommended on SSRX channel.

            Are both type-A and type-C  are receptacle ? Where did you get pinout information for HD3SS6126? pin 35-38 should be NC pin and only has 1one SEL and  one HS_OE

    Regards

    Hi Brian,

    Thanks for your great support.

    In addition, when HD3SS6126 is compatible with USB Type-C 5G NR LTE Device, how to determine the corresponding method of Switch? Thank you.

    Many Thanks,

    Jimmy

    Jimmy:

        To find the corresponding method of Switch, you need to check if the switch bandwidth is high enough for the device . Next you need to check the application  signal (like USB3) amplitude and common mode voltage is meet switch spec. so what is  amplitude and common mode voltage of 5G LTE?

       I still need to know  if  type-A and type-C  are receptacles or not ? it's important  for the design

    Regards
