Solution: Design the CAN network with proper topology and avoid excessive branching. Terminate each end of the bus with a 120Ω resistor. 4. Summary

By addressing these key factors—impedance matching, proper termination, cable management, grounding, and EMI shielding—you can effectively solve the signal reflection and noise problems when using the SN65HVD230DR. The following steps provide a simple checklist for troubleshooting:

Check the cable type and impedance. Ensure proper termination at both ends of the bus. Minimize cable length and use high-quality cables. Use shielded cables to protect from EMI. Check and improve grounding. Verify the power supply is clean and stable. Use filters and snubbers for additional noise suppression. Follow the correct network topology and avoid excessive branching.

By following these steps, you should be able to improve the performance of your CAN network and resolve signal reflection and noise issues effectively.
