HD3SS3415: Support need on recommend a mux support usb3.1 and PCIe 3.0

Part Number: HD3SS3415
Other Parts Discussed in Thread: HD3SS3412A, TMUXHS4412, , HD3SS3412

Hi team,

      Our customers want a mux support the 4 channel 1:2 and usb3.1 (10Gbps if it could support the PCIe 3.0). The more details are shown below.

    1. I find that  HD3SS3415 TMUXHS4412  HD3SS3412A HD3SS3412 seem to meet the customers' need. Could you please confirm that?(I find that most device do not meet supply voltage and temperature)

    2. And Could you please recommend a device to meet the customers' need?

    3. In addition, what are the differences between the HD3SS3412A  and HD3SS3412 ?

传输协议[Protocol] USB3.1
拓扑结构[Topology] four channel 1:2
最小供电电压[VDD(Min.)] ＜1.5V
最大供电电压[VDD(Max.)] ＞5V
带宽[Bandwidth] ＞10G
其他特性[Other Features] It is better to support multiple protocols such as PCIE Gen3
Operating temperature Min -40℃
Operating temperature Max 85℃

    nan:

        we only have HD3SS3212q1 support -40 to 85c,  it's BW is 8Ghz, but  it support USB3.1

    Hi Brain,

         Thanks for your reply.

         1.After talking with customer, the request from customer on bandwidth is more than 10Gbps instead of 10GHz,so the HD3SSS3121q1 could meet the their need(only use for usb mux).

         2.If the temperature and voltage constraints are ignored first, can HD3SS3415 TMUXHS4412 HD3SS3412A HD3SS3412 ,these material devices meet customer requirements?

         3.For the need on mux, it is necessary for device to support usb mux. If our products could act as PCIe mux too, it would help us to have better chance to win.

    2: if emperature and voltage constraints are ignored first, HD3SS3415 TMUXHS4412 HD3SS3412A HD3SS3412meet customer needs too.

    3: those Mux all support both USB3 and PCie gen3, TMUXHS4412  suport PCIe Gen 4.

    Hi Brain, 

         Thanks for your confirm.

         1.But I find HD3SS3412 and TMUXHS4412 could work at -40℃ according to datasheet. Could you please confirm these?

         2.Could you please tell what the differences between the HD3SS3412 and HD3SS3412A expect operating temperature?
