Other Parts Discussed in Thread: HD3SS6126, TUSB8041, HD3SS6126EVM

Hye bro,

Hereby I had attached 4:1 MUX USB 3.0 using HD3SS6126 (Multiple). Can your team check it out either the PIN CONFIGURATION especially for HD3SS6126 which I had drawn are correct or not ?

Kindly waiting for your reply.

    Hello,

    Cascading HD3SS6126 could probably cause signal integrity issues because the switches are passive and will not regenerate the signal.

    We recommend to use a USB 3.0 Hub like the TUSB8041.

    Is there a reason for you to not use a USB hub?

    Regards.

    Hye bro..

    If I use hub its like many to one connection since I can't control which hub(host) I will choose. But by using the HD3SS6126 I can choose which host I want respectively (SEL Pin)

    Since I had bought 2 HD3SS6126EVM and it works when I multiple it together. Hereby I had attached the connection which I did using this 2 HD3SS6126EVM.

    Based on the data sheet for HS3SS6126 the pin number 42, 2, 3, 41 ,38, 37, 36 and 35 are NC (No connection). But  in the HD3SS6126EVM there are connection for those pins. Can you guys tell me what is the functionality of those pin.

    According to my design which I posted for 4:1 I didn't consider pin number 42, 2, 3, 41 ,38, 37, 36 and 35 because its NC in data sheet.

    Hello,

    That EVM was designed to accommodate to other devices not only the HD3SS6126.

    Please follow the HD3SS6126 datasheet.

    Regards.
