6 Benefits of CAN SIC

CAN SIC transceivers provide significant system benefits over regular CAN-FD transceivers without the need for design changes on the physical or application layer. These transceivers enable operation at faster bit rates, with more freedom in choosing a network topology, while reducing vehicle cost and weight.

CAN SIC is backwards-compatible to ISO 11898-2, so it can operate on the same bus as CAN-FD.

As shown in Table 1-1, CAN SIC transceivers significantly improve bit-timing symmetry, which enables more margin for any network effects that can deteriorate CAN signals. The transceiver introduces much less degradation to the transmitted and received bits, reducing the bit duration to operate reliably at 8 Mbps. And finally, the loop delay of CAN SIC transceivers is 190 ns max, compared to 255 ns max for CAN-FD transceivers, helping extend the maximum network length.
