SN65LVDS389DBT datasheet by Texas Instruments

SN65LVDS389DBT Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS389DBT?
  The maximum cable length supported by the SN65LVDS389DBT is approximately 10 meters (33 feet) at a data rate of 1.485 Gbps. However, this length can vary depending on the specific application, cable quality, and environmental conditions.
• How do I ensure signal integrity with the SN65LVDS389DBT?
  To ensure signal integrity with the SN65LVDS389DBT, it is recommended to use a differential pair for the LVDS signals, keep the traces as short as possible, and use a common mode choke or ferrite bead to filter out electromagnetic interference (EMI). Additionally, the use of a shielded cable and a grounded shield can help reduce EMI.
• What is the power consumption of the SN65LVDS389DBT?
  The power consumption of the SN65LVDS389DBT depends on the operating frequency and the output load. At a typical operating frequency of 1.485 Gbps, the power consumption is approximately 350 mW. However, this value can vary depending on the specific application and operating conditions.
• Can the SN65LVDS389DBT be used in a multi-point configuration?
  No, the SN65LVDS389DBT is designed for point-to-point applications only. It is not suitable for multi-point configurations, as it does not have the necessary circuitry to support multiple receivers or transmitters.
• What is the maximum operating temperature range of the SN65LVDS389DBT?
  The maximum operating temperature range of the SN65LVDS389DBT is -40°C to 85°C. However, the device can be operated at temperatures above 85°C for short periods of time, but this may affect its reliability and lifespan.
