TS3USB3031: connect outputs parallel?

Hi Hans,

What do you mean by doubling the output current? Do you want to have the signal come in from MHL+/- or USB1/2 +/- and come out of D+/D- and come together to double the current of the same signal?

Please let me know.

Thanks,

Ryan

Hi Ryan,

maybe my question was not precise because there is no real output;-)

Is it possible to parallel the 2 internal muxes and use them as a one channel mux? And yes, the idea is to double the current.

Thank you and Best Regards, Hans

Hi Ryan,

we have single-ended signals with a max. current of 100mA.

The idea was using + and - Pin on TS3USB3031 to reduce current per Pin

Thanks,

Gerhard

Hi Gerhard and Hans,

As far as I am aware, no, this is not an implementation we can support with this mux. 

Please let me know if you have any other questions,

Thanks,

Ryan

Hi Ryan,

can you give us a reason why this is not possible, please? 

Thank you and Best Regards, Hans

Hello Hans,

As a first order look into this there are multiplexers that can handle the max 100ma current through the switch. One example is the TMUX8212 which is a 1:1 four channel device but can be made into a 4:1 1 channel if you tie all the output pins together.

Would this satisfy your requirements?

In addition is the 1ghz signal in your system a requirement? Could you please explain this further?

Kameron

Hello Kameron,

as previously written the required bandwidth is 1GHz. Supply should be 2.5V ...3.3V.

You did not answer my question why the TS3USB3031 switches are not allowed to connect in parallel.
