CAN Interface

The OEM617D provides two 2.7 V (3.3 V-compatible) CMOS-level CAN controller ports. An external
transceiver is required. The following figure shows a typical CAN transceiver implementation.
The combination of ferrite beads and small value capacitors are not necessarily required but may provide
improved EMI performance. A low capacitance TVS device provides ESD protection.
Figure 55: OEM617D CAN Transceiver Implementation Schematic
Only use a 120 Ω termination resistor when the CAN device is used at one end of the CAN bus. Multiple
terminations along the length of the CAN bus will degrade performance for all CAN devices on the bus.
The slew rate adjustment resistor (R101) value in Figure 55 on page 120 sets the slew rate for
applications for SAE J1939 agricultural applications. Other applications may require a different slew rate.
Refer to the transceiver product sheet for more information.
