Hallo,
1) Would you please let me know how to calculate maximum stub length in CAN bus network?
Is there any method to estimate maximum stub length in order to avoid the reflections (using the ISO1050 at 500Kbps. Maximum rise/fall time of ISO1050 is 50ns in the datasheet.)?
Though the ISO11898 Standard specifies a maximum bus length of 40m and maximum stub length of 0.3m at 1Mbps.
2) In the customer application, the ISO1050 output has two branch output lines. One output line is optional and ordinarily not use.
Does this optional line need any termination, though I think it’s okay to leave it open?
Best Regards,
Kazu Ogawa
