SN65HVD1781DR Frequently Asked Questions (FAQ)

  • The maximum cable length supported by the SN65HVD1781DR is dependent on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths of up to 100 meters at a data rate of 100 Mbps.

  • To ensure signal integrity and minimize EMI, it is recommended to use a shielded cable, keep the cable away from noise sources, use a common-mode choke, and follow proper PCB layout and grounding techniques.

  • The recommended termination scheme for the SN65HVD1781DR is a 100-ohm differential termination resistor at the receiving end of the cable, as close to the receiver as possible.

  • Yes, the SN65HVD1781DR can be used in a multi-point or multi-drop configuration, but it requires additional circuitry and careful design consideration to ensure signal integrity and avoid data corruption.

  • To troubleshoot issues with the SN65HVD1781DR, use a logic analyzer or oscilloscope to capture and analyze the signal waveforms, check the cable and connector integrity, and verify the device configuration and programming.
