Bertl: anuejn: some preliminary simulation result for the levelshifter https://f.coroot.de/20240611_18h55m03s_grim.png (I am not 100% yet that this is correct, so take with a grain of salt)

iirc 70pF is the maximum capacitive load that we have to support for mipi lp, and 15%-85% rise time has to be at most 25ns, so it seems like this levelshifter should work

nice

that sounds good

(and the simulation is the min corner of the device)

(code for the ibis -> spice conversion here: https://github.com/rroohhh/kibis2spice) basically just the kicad internal code extracted to be standalone

nice

very handy

nice, and we expect that <=70pf is what we get with the flat cable and the typical MIPI receiver?
