SN65LVDS31DG4 Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS31DG4?
  The maximum cable length supported by the SN65LVDS31DG4 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 SN65LVDS31DG4?
  The SN65LVDS31DG4 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 SN65LVDS31DG4?
  The power consumption of the SN65LVDS31DG4 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 SN65LVDS31DG4 for non-LVDS applications?
  While the SN65LVDS31DG4 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, and additional circuitry or components may be required.
• How do I handle electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues with the SN65LVDS31DG4?
  To minimize EMI and EMC issues, ensure proper PCB layout, use shielding, and follow good design practices for differential signaling. Additionally, consider using EMI filters or common-mode chokes to reduce emissions and improve immunity.
