TCAN1048AV-Q1: question about CAN FD communication speed performance

Hi Jay,

Please refer to this thread.

Hi Jay,

Whether can reach a specific data rate or not is a system level question, TI does not build or test a system, all the boards we build (like a EVM) and test are only on the ECU level. Thus, customers need to test in their own system to get the most accurate result.

To be a little bit more specific, 8Mbps is only theoretical maximum the chip can support, but not in a real application. It may be possible in a simple node to node network, with PCB board carefully designed, CMC required. 5Mbps is possible but difficult to realize in real system, the network need to be ideal, no impedance mismatch on board & cabling. For this reason, CAN SIC is highly recommended if customer want 5Mbps communication which can save them a lot of efforts on designing the system.
