SN65LVDS31DR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS31DR?
  The maximum cable length supported by the SN65LVDS31DR is approximately 10 meters (33 feet) at a data rate of 655 Mbps. However, this length can vary depending on the specific application, cable quality, and noise environment.
• How do I terminate the differential lines in the SN65LVDS31DR?
  The SN65LVDS31DR requires a 100-ohm differential termination resistor at the receiver end to ensure signal integrity. The termination resistor should be placed as close to the receiver as possible.
• What is the power consumption of the SN65LVDS31DR?
  The power consumption of the SN65LVDS31DR depends on the operating frequency and output load. At a typical operating frequency of 65 MHz, the power consumption is approximately 135 mW. However, this value can vary depending on the specific application and operating conditions.
• Can I use the SN65LVDS31DR for non-LVDS applications?
  While the SN65LVDS31DR is designed for LVDS applications, it can be used for other differential signaling applications with some limitations. However, the device's performance and signal integrity may not be optimal for non-LVDS applications.
• How do I handle electromagnetic interference (EMI) with the SN65LVDS31DR?
  To minimize EMI, it is recommended to use shielded cables, keep the transmitter and receiver close together, and use a common-mode choke or ferrite bead to filter out high-frequency noise.
