I would like to connect TJA1027 LIN controller to a 3.3V interface on a FPGA. The datasheet shows the following application diagram. To work with a 3.3V FPGA interface, do I just need to add a pull the RXD signal (open-drain output) to 3.3V, not matter of the VBAT voltage on the other side of TJA1027? If this is correct, what pull-up resistance value should I use?
Is there anything else I need to to on TXD and SLP_N signals (input)?
