TS5A23159: To use analog switch instead of usb switch

Part Number: TS5A23159
Other Parts Discussed in Thread: TMUX136

Hello Expert,

Our customer has already been using TS5A23159, TS5A4624DCKR on their product.

So they want to use this part for USB 2.0 data instead of USB protocol-specific switches & muxes.

When I checked bandwidth, I think that there is no issue.

But I'm not sure whether there is problem or not.

So I need your confirm and explain about below block diagram.

I'm looking forward to receiving your feedback ASAP.

Best regards,

Michael

    You can use any switch that supports the required bandwidth and voltage range.

    These devices can support full speed (12 Mbps) but not high speed (480 Mbps).

    Hi Michael,

    As Clemens mentioned, both switches are rated for ~100MHz bandwidth which is likely too slow for high speed USB 2.0. Please confirm the bandwidth requirements with your customer.

    If a higher bandwidth device is needed, the TMUX136 would be a good fit for this application. It is a 2 channel 2:1 switch with 6GHz bandwidth.

    Thanks,

    Tyler
