SN65LVDS100DGKR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS100DGKR?
  The maximum cable length supported by the SN65LVDS100DGKR 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 ensure signal integrity with the SN65LVDS100DGKR?
  To ensure signal integrity with the SN65LVDS100DGKR, it is recommended to use a differential pair for the LVDS signals, keep the signal traces short and well-matched, and use a common mode choke or ferrite bead to filter out common mode noise.
• Can I use the SN65LVDS100DGKR for non-LVDS applications?
  While the SN65LVDS100DGKR is designed for LVDS applications, it can be used for other differential signaling applications such as RS-422 or RS-485 with some modifications to the circuit design and component selection.
• How do I handle power sequencing with the SN65LVDS100DGKR?
  To ensure proper operation, it is recommended to sequence the power supplies to the SN65LVDS100DGKR such that the analog power supply (VCCA) is powered up before the digital power supply (VCCD).
• What is the recommended layout and routing for the SN65LVDS100DGKR?
  For optimal performance, it is recommended to follow good layout and routing practices such as keeping the LVDS signal traces short and well-matched, avoiding vias and right-angle bends, and using a solid ground plane to reduce electromagnetic interference (EMI).
