Hi All - Anybody expert on CAN termination ? I'm looking at a board with the standard CAN terminator (120 ohm split into two60 ohm with a 6.4pf to ground in the middle). The board also has a choke on the CAN input (CHOKE DOUBLE .051MH 500MA SMD EPCOS B82790S0513N201).
All this looks OK except: The terminator is placed behind the choke. Doesn't that reduce the effectiveness of the termination (especially the cap which helps to damp any HF noise) ?
I searched about but didn't find any references... Any pointers ?
Thanks in advance, Best Regards, Dave
