i.mxrt1170: CAN Bus trace impedance controller

[haryanl]

Hi NXP team,

we are designing a CAN FD Port (RT1170 +TJA1057BT/0Z)
can you tell us is it necessary to control (CANH/CANL) trace impedance as differential signal? And if yes, how many Ohm (120Ohm?) to control
or like Single-Ended Signal (50Ohm) is enough

Thanks,

Huy

Hi @haryanl ,

Thanks for your interest in NXP MIMXRT series!

Yes, and the target impedance is 120 ohm. The schematic you provided is referenced to the correct section.

Best regards,
Gavin
