The maximum cable length supported by the SN65HVD1787DR 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 transmitter and receiver pairs close together, and use a common-mode choke or ferrite bead to filter out high-frequency noise.
For optimal performance, it is recommended to follow a differential pair routing scheme, keeping the transmitter and receiver pairs close together and avoiding vias and right-angle turns. Additionally, it is recommended to use a solid ground plane and to keep the device away from noise sources.
To troubleshoot issues with the SN65HVD1787DR, it is recommended to use a logic analyzer or oscilloscope to monitor the signal quality and identify any errors or anomalies. Additionally, checking the power supply voltage, signal termination, and cable quality can help identify the root cause of the issue.
Yes, the SN65HVD1787DR is suitable for use in industrial and automotive applications due to its high temperature range (-40°C to 125°C) and robustness against electromagnetic interference (EMI) and electrostatic discharge (ESD).
