Hello,
Our current products are all using SN65HVD230 CAN transceivers (3.3V).
They are working correctly, and when we perform tests using a 30m cable with a 1Mbit/s rate the communication is working according to ISO11898-2 requirements.
I need to design a new product with an isolated CAN transceiver.
My microcontroller is using a 5V power supply. For this reason I decided to use a ISO1050 isolated CAN tranceiver.
The prototype is working fine
BUT :
Using a 30m cable between my old products (using SN65HVD230) and this new product (using IS1050) the communication is not working (at 1Mbit/s rate).
I need to reduce the cable length from 30m to 16m to make it work !!!
Question :
Is there a compatibilité issue between 3.3V and 5V transceivers ?
Do you have any idea about this issue ?
Thank you,
David
