TMS320F28379D: To find the actual baudrate from TLE94713ESV33XUMA1 to TMS320F28379D

Ananthu V

Part Number: TMS320F28379D

Hi support Team,

I would like to know how this components as attached here in schematics affects the actual baud rate from this IC"TLE94713ESV33XUMA" to TMS320F28379D. CAN max baud rate is 5Mbit/s from this IC. What exactly the baud rate is received at the TMS320F28379D CAN. Please share the formulas if any for finding the actual baud rate after losses from these connected elements.

28379D has the CAN module whose bit-rate is capped at 1 Mbps. The components you pointed out do not impact the bit-rate. If you are new to CAN, there are excellent introductory videos at https://training.ti.com/search-catalog?keywords=CAN&start%5Bdate%5D=&end%5Bdate%5D=

The components you highlighted do not impact the bit-rate in anyway. R1,R2 & C61 are part of the split-termination. D1 is for ESD protection. L2 is a common-mode choke.

5Mbps is the max CAN FD bit-rate supported by this IC. 28379D has classic CAN with max rate of 1 Mbps.

Same as what is transmitted on the bus.
