ADM3053 baud rate problem

The ADM3053 is compliant with ISO11898. Whether its baud rate range is 150kbps-1Mkbps, the minimum baud rate is 150kbps. Can you have a lower baud rate?

    ADM3053 has no minimum baud rate, because it has no "dominant timeout" (it won't bring CANH/CANL recessive even if TXD is still held low for a long time). The part will operate normally even at very low bit rates.

    If dominant timeout is needed as well as low data rates (but only to 9600 bps), ADM3055E provides similar functionality (with improved iso DC-DC, isolator and CAN transceiver performance). ADM3055E minimum data rate is 9600 bps due to the dominant timeout function.
