1.4 Device Information

The CAN EVM has simple connections to all necessary pins of the CAN transceiver device, and jumpers where necessary to provide flexibility for device pin and CAN bus configuration. There are test points (loops) for all main points where probing is necessary for evaluation such as GND, VCC, TXD, RXD, CANH, CANL, pin 8 (mode pin), or pin 5 (various functions). The EVM supports many options for CAN bus configuration. The CAN EVM allows for two termination schemes through a single jumper to select between just split termination configuration, or split with 120Ω resistor as well. If needed, there are footprints for a common-mode choke, TVS diode for ESD protection, and capacitors for further EMC protection, or signal conditioning. A DSUB9 connector is included to allow the evaluation and use of the CAN bus in larger systems.
