SN65LVDS20DRFT Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS20DRFT?
  The maximum cable length supported by the SN65LVDS20DRFT is approximately 10 meters (33 feet) at a data rate of 655 Mbps. However, this can vary depending on the specific application and cable quality.
• How do I terminate the differential pairs in the SN65LVDS20DRFT?
  The SN65LVDS20DRFT requires a 100-ohm differential termination resistor at the receiver end. This can be achieved using a 100-ohm resistor in series with a 0.01-uF capacitor to ground.
• What is the power consumption of the SN65LVDS20DRFT?
  The power consumption of the SN65LVDS20DRFT is approximately 135 mW at a supply voltage of 3.3V and a data rate of 655 Mbps.
• Can I use the SN65LVDS20DRFT for non-LVDS applications?
  While the SN65LVDS20DRFT is designed for LVDS applications, it can be used for other differential signaling applications such as RS-422 or RS-485 with proper termination and signal conditioning.
• How do I ensure signal integrity with the SN65LVDS20DRFT?
  To ensure signal integrity with the SN65LVDS20DRFT, it is recommended to use a shielded cable, maintain a consistent impedance throughout the transmission line, and minimize electromagnetic interference (EMI) and radio-frequency interference (RFI).
