TS5MP646: (TMUX646 Pin-to-pin upgrade supporting 6-GHz bandwidth available) Recommended products

Hi sir,

What MIPI CSI-2 switch product would you recommend in present TI catalog?

which one have higher speed?

Do you have a EVM or design kit to test high speed switching? 

Also, does TI have a microprocessor that can handle 2 or more MIPI CSI-2 ports?

BTW, does TI have a gigabti Ethernet hub controller , and what number of ports?

Can I series connect 2 stage MIPI switches in my design?

Thanks,

regards,

    Yumiko,

    Any recommendation would be based on your use case. Given that you're looking for a MIPI switch i'd say that you're in the right place, though.
    The TS5MP646 has the highest bandwidth. The TS5MP645 is a very similar device but a lower speed at 1.5GHz vs the 3GHz the TS5MP646. To compare the speeds or a variety of other specs, on the product search page you can sort out the spec you're interested in.

    If the product has an EVM, this information will be found on the product page under the 'Design & Development' tab. It looks like we have EVM's for the TS5MP645 and TS5MP646 but not the TSD36227. However, there are simulation models that you could use to simulate use cases.   



    As for your question regarding the microprocessor and ethernet hub controller, do you have a block diagram to give me a better understanding of what you're looking for? How many channels do you need for the ethernet hub controller? I'm going to loop in someone who has more knowledge with those products to ensure we answer this properly. In the meantime, you can always view TI's processor page and see if you can find what you're looking for. https://www.ti.com/processors/overview.html

    Finally, i'm not sure what you mean by 2 stage MIPI switches in series. If your intent is to essentially daisy chain these to increase your 2:1 MIPI switch to effectively a 4:1 or greater, this shouldn't be too much of a problem, depending on how much you had in mind. These lines are really just analog data lines that have been designed in a way to be compatible for MIPI applications. Just be weary of the resistance and capacitance added as you increase the amount. While these are low R-on and low C-on devices but the accumulation can add up quickly.  

    Hope this helps,
