    Hi Nithya,

    Thanks for sharing your question on E2E!

    The TCAN4550 can support all of the protocol layer requirements listed here. Any of our 5V CAN transceivers will also be able to support the physical layer requirements listed. The TCAN4550 can be configured in "test mode" (which is suitable for application use cases) in order to break to the TXD and RXD pins for use with an external transceiver. This would allow for these signals to be run through a digital isolator or connected directly to an isolated CAN transceiver such as the ISO1044. 

    See the thread linked below for more information on how this can be implemented in a system.

    Let me know if you have any more questions.
