Hi team,

For TCAN1043 application, is below ok? There are RTERM of each node, thanks!

Hi Jiawei,

Yes this is OK. You can place large-valued termination resistor on multiple nodes, but you need to ensure the overall termination of the bus is ~60 Ohm. I would recommend to read this previous thread:

... in other words: if these are 120 Ω resistors, then this is definitely not OK.
