CAN Communication Control Circuit
CAN communication control circuit is incorporated into the control unit and transmits/receives CAN communication signals.
| Component | System description |
|---|---|
| CAN controller | It controls CAN communication signal transmission and reception, error detection, etc. |
| Transceiver IC | It converts digital signal into CAN communication signal, and CAN communication signal into digital signal. |
| Noise filter | It eliminates noise of CAN communication signal. |
| Termination circuit* (Resistance of approx. 120 Ω) | Generates a potential difference between CAN-H and CAN-L. |
*: These are the only control units wired with both ends of CAN communication system.
