SN65LVDS9638D datasheet by Texas Instruments

SN65LVDS9638D Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS9638D?
  The maximum cable length supported by the SN65LVDS9638D 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 and minimize electromagnetic interference (EMI) when using the SN65LVDS9638D?
  To ensure signal integrity and minimize EMI, use shielded cables, keep the transmitter and receiver close together, use a common ground plane, and follow proper PCB layout and routing guidelines. Additionally, consider using EMI filters or common-mode chokes to reduce emissions.
• What is the recommended termination scheme for the SN65LVDS9638D?
  The recommended termination scheme for the SN65LVDS9638D is a 100-ohm differential termination resistor at the receiver end. This helps to reduce reflections and improve signal quality.
• Can I use the SN65LVDS9638D for non-LVDS applications, such as TTL or CMOS?
  No, the SN65LVDS9638D is specifically designed for LVDS applications and is not compatible with TTL or CMOS signals. Using it with non-LVDS signals may result in incorrect operation or damage to the device.
• How do I handle hot swapping or plug-and-play applications with the SN65LVDS9638D?
  To handle hot swapping or plug-and-play applications, use a hot-swap controller or a power sequencer to ensure that the power supply is stable before enabling the transmitter. Additionally, consider using a fault-tolerant design to prevent damage to the device or other components.
