Dear Technical Support Team,

I have a question about SN65HVD251.

Do you have a point to notice for impedance control of CANH and CANL on PCB design?

Best Regards,

Hello ttd,

CAN is typically used with cabling that has a 120-Ohm differential characteristic impedance, so it is best if the PCB traces are routed as 120 Ohm differential or 60 Ohms single-ended.
