second do we have AUTO grade MIPI MUX, could you help recommend a suitable AUTO grade device.

    The N indicates that the same chip is packaged on a different reel; see p. 32 of the datasheet.

    There are no automotive-qualified, high-speed switches; the fastest would be the TMUX1309-Q1 with 0.5 GHz.

    Hi Colt,

    Clemens is spot on here. The difference between the two OPN's has to do with the reel differences, which you can see starting with page 32 of the datasheet. 

    May I ask who the customer is? We have a similar E2E post where a similar topic was discussed. For a single chip solution, we currently don't have an automotive solution. The post breaks down how the SN3257-Q1 could be used as a multi-chip solution. 

    Thanks!
