TMUX646: Does it support USB3.1 with rate at 5Gbps?

Hey Nan,

What is the frequency bandwidth of the USB3.1? Transmission rate is 5Gbps but this doesn't necessarily correlated to the frequency bandwidth (See : [FAQ] How do I Select the Right Analog Switch/Multiplexer Bandwidth Based on the Data Rate of my Protocol?).
Typically, we would recommend a device that has at least 1.5x the bandwidth of the signal you're trying to pass through. I suspect that 5gbps would be the transmission rate but the frequency bandwidth would be closer to half of that, which would make this more than suitable for their application. 
Another thing that would determine whether or not this device would work would be the voltage of the CAN bus. Do you know what they're operating at?

Thanks,
Rami

Hi Rami,

     Thanks for your quick reply and the learning link.

     Based on the double data rate of USB protocol(the red mode in link), 5Gbps need 2.5GHz of bandwidth. So 2.5GHz*2<6GHz. So it seems meet the customer's need. Am I right?

     As for CAN, the customer said that the maximum voltage in CAN bus is 5V. The range of TMUX646 is 1.5-5.5V. So it seems work.

     All in all,  the TMUX646 is suitable for the customer's design. Am I right?
