SN65HVD10QDR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD10QDR?
  The maximum cable length supported by the SN65HVD10QDR is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 100 meters at 9600 bps and 10 meters at 1 Mbps.
• How do I ensure electromagnetic compatibility (EMC) with the SN65HVD10QDR?
  To ensure EMC with the SN65HVD10QDR, follow proper PCB layout and design guidelines, use a common-mode choke or ferrite bead on the bus, and ensure proper shielding and grounding of the device and cables.
• What is the recommended termination resistor value for the SN65HVD10QDR?
  The recommended termination resistor value for the SN65HVD10QDR is 120 ohms, but this may vary depending on the specific application and cable characteristics.
• Can the SN65HVD10QDR be used in a multi-drop configuration?
  Yes, the SN65HVD10QDR can be used in a multi-drop configuration, but it requires careful consideration of the bus topology, cable lengths, and termination resistors to ensure reliable operation.
• How do I handle bus fault detection and fault tolerance with the SN65HVD10QDR?
  The SN65HVD10QDR has built-in fault detection and tolerance features, including overvoltage protection, undervoltage protection, and short-circuit protection. Additionally, external fault detection circuits can be implemented using voltage monitors and fault detection ICs.
