Texas Instruments provides a recommended layout and routing guide in their application note SLVAE67, which includes guidelines for PCB layout, component placement, and routing to ensure optimal performance and minimize electromagnetic interference (EMI).
The TCAN3403DRQ1 can be configured for different CAN bus speeds by adjusting the values of the termination resistors (R1 and R2) and the biasing resistors (R3 and R4). The datasheet provides a table with recommended values for different bus speeds. Additionally, the device can be configured using the SPI interface to adjust the slew rate and output voltage.
The maximum cable length supported by the TCAN3403DRQ1 depends on the bus speed and the type of cable used. As a general rule, the maximum cable length for a CAN bus is 40 meters at 1 Mbps and 10 meters at 10 Mbps. However, the actual cable length may be shorter due to signal attenuation and reflections. It's recommended to consult the CAN bus specification and perform signal integrity analysis to determine the maximum cable length for a specific application.
To ensure EMC with the TCAN3403DRQ1, it's recommended to follow proper PCB design and layout practices, such as using a ground plane, minimizing trace lengths, and using shielding and filtering components. Additionally, the device should be placed in a metal enclosure and connected to a chassis ground to reduce radiated emissions. Texas Instruments also provides EMC guidelines in their application note SLVAE67.
The power consumption of the TCAN3403DRQ1 depends on the operating mode and the bus speed. In normal mode, the device consumes around 12 mA at 3.3 V and 10 mA at 5 V. In standby mode, the device consumes around 1 mA. The power consumption can be further reduced by using the low-power mode, which consumes around 0.1 mA.
