Dear TI Team,
We are using TCAN1042HVDRQ1 CAN Transceiver in our Design.
We are facing some issue in RE test(Failure Frequency 200Mhz to 230 Mhz and 380Mhz to 420Mhz).
I have attached the schematic view of our CAN Transceiver design.
We are suspecting that, Mounting split termination, High impedance CMC and Bus filter may help out for our RE testing.
Kindly suggest the Capacitor, CMC value for our testing.
i)Bus Filter Capacitor(C289,C297,C298,C290) not Mounted on the device. Please suggest what capacitor value to be mounted for better RE performance/ reduce the ripple?
ii)Please suggest What capacitor value to be mounted for split termination(C287)?
iii)Currently we have mounted 360 ohm CMC (E6) in CAN bus path. Please let us know, any other value to be mounted to reduce the noisy peak in RE testing.
Also please share the Radiated EMI application report of TCAN1042HVDRQ1 transceiver.
