Guides
Practical articles on designing CAN and CAN-FD buses, with the formulas and the values to use.
How long can a CAN-FD stub be?
Reflections at the junction, a first-order rule for stub length, the classic 0.3 m limit, and how bit rate and sample point change the picture in CAN-FD.
CAN termination: how many, where, and what goes wrong
Two 120 Ω terminations at the ends of a linear High-Speed CAN backbone: the DC load, what ISO 11898-2 really specifies, and what happens with one termination or too many.
Reflections in a CAN-FD bus: the Γ coefficient explained
Differential characteristic impedance, the reflection coefficient, when transmission-line effects matter, and why parasitic capacitance and ESD diodes count in CAN-FD.
