Part Number: TUSB501-Q1

Hi, team,

We would like to place TUSB501-Q1 for USB3.0 with type-C port. Two questions may need your help on reply.

1. Is the re-driver only suggested to place at receiver side?

2. For type-C port, there is RX1+/- and RX2+/-,can we just connect RX1 and RX2 together on board and place one piece of TUSB501-Q1 for receiver side re-driver?

Thanks.

Johnny

    For Type-C USB only, please consider TUSB542 (5G USB) or TUSB1042 (10G). 

    For source side USB Alt Mode, please consider TUSB546 or TUSB1046.

    For sink side USB Alt Mode, please consider TUSB564 or TUSB1064.

    Thanks

    David,

    Thanks for reply. We need AEC-Q100 version USB3.0 re-driver for type-C port. Have you some suggestion?

    Unfortunately we currently do not have a AEC-Q100 version Type-C solution available.

    Thanks

    We do not have a single chip solution available, but you could consider HD3SS3212-Q1 and two TUSB501-Q1 for AEC-Q100.

    Thanks

    David,

    If the end equipment is only a USB HUB, small board, can we just place one TUSB501-Q1 at RX side, and no re-driver for TX side?

    Thanks.

    It depends on the hub driving capability and the total insertion loss (including the small board) on the TX side. If the total insertion loss is within the hub TX driving capability, then you don't need the TUSB501-Q1, otherwise you would need it.

    Thanks
