Design‑In Guidance (General Best Practices)

While detailed electrical parameters must come from the datasheet, the following general practices can help teams integrate the Texas Instruments SN65HVD1040QDRQ1 efficiently:

• CAN bus termination: Use 120‑Ω termination at the ends of the bus. In stubs and branch topologies, maintain short stubs to limit reflections at higher bit rates like 1 Mbps.
• EMC and layout: Keep the CANH/CANL differential pair tightly coupled and routed with consistent impedance. Provide a solid return path and minimize loop area. Place any required transient suppression devices and common‑mode components close to the transceiver and connector as dictated by system‑level EMC testing.
• Grounding strategy: Maintain a clean ground reference near the transceiver. In mixed‑signal ECUs, segregate high‑dI/dt power paths from sensitive I/O routing.
• Power decoupling: Bypass the 5‑V supply with appropriately sized ceramic capacitors located close to the VCC pin. Follow TI’s datasheet and application notes for recommended values and placement.
• Bit rate planning: 1 Mbps is supported for classical CAN. Ensure cable length, node count, and stub lengths are consistent with your chosen bit rate for sufficient timing margin.
• Temperature considerations: The −40°C to +125°C operating range supports under‑the‑hood and cabin modules. Validate thermal performance in‑system, accounting for ambient conditions and enclosure constraints.

These practices are general to ISO 11898‑2 classical CAN implementations and help achieve the EMC and reliability objectives that the SN65HVD1040QDRQ1 is designed to support.
