CAN FD Network Design Hints and Recommendations 2016-01-0060
The CAN FD protocol internationally standardized in ISO 11898-1:2015 just describes how to implement it into silicon. The ISO 11898-2:2016 standard specifies the physical media attachment (PMA) sub-layer of the CAN (FD) physical layer. The design of CAN FD networks is not in the scope of these standards. In general, the physical layer design of CAN FD networks requires more attention compared with Classical CAN networks. First recommendations have been developed. Different standardization bodies have already specified or are in the process of specifying higher-layer protocols, for example ISO for on-board diagnostic, ASAM for calibration, etc.
