Re: CAN bit timing, Seg2 =1Tq

Hi,
The cable is a controlled 120 OHM cable (5nS/m) by Axon Cables . Don't
recall the exact p/n. I would like to extend the bus to about 30m.
The dominant to recessive loop worst case delay is 400nS, there are 16
nodes nodes. All nodes clocks' use XOs - several ppm accuracy.
What the risk of edgy sampling? it is still 125nS in.

Regards,
ab
