CAN bus with 60 ohm termination? - Reimagining Education

WebA split bus termination, consisting of two identical resistors (60 Ohm) and one capacitor (typically 4.7 nF), acts like a low-pass filter; high-frequency signals are shunted to ground without affecting the d.c. voltage relationships. Measurements have shown that this can improve noise immunity and reduce emissions. WebA CAN bus terminator can be used for termination of any high speed (ISO 11898-2) CAN bus system. The 120 Ohm terminating resistor is setup between pin 2 (CAN low) and pin 7 (CAN high). In general, ISO 11898-2 CAN networks must be terminated at each end using 120 Ohm terminal resistors.
