We do not have IBIS models for any UART yet but here are the measurements that we can offer:
SDO rise/fall times:
V=1.71V / rise à 14.1 / 15.0 / 16.1 ns [-40 / 25 / 85 C]
V=1.71V / fall à 13.7 / 15.2 / 21.1 ns [-40 / 25 / 85 C]
Unfortunately, we don’t have data for any other voltage levels.
The customer could use this as a baseline for logic outputs.
