SN65LVDS100D datasheet by Texas Instruments

SN65LVDS100D Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS100D?
  The maximum cable length supported by the SN65LVDS100D 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 LVDS outputs of the SN65LVDS100D?
  The LVDS outputs of the SN65LVDS100D should be terminated with a 100-ohm differential load to ensure proper signal integrity and to minimize reflections. A 100-ohm resistor can be connected between the positive and negative outputs of each channel.
• What is the power consumption of the SN65LVDS100D?
  The power consumption of the SN65LVDS100D depends on the operating frequency and the output load. Typically, the device consumes around 150 mW of power when operating at 65 MHz with a 3.3V supply voltage.
• Can I use the SN65LVDS100D with a 2.5V supply voltage?
  Yes, the SN65LVDS100D can operate with a 2.5V supply voltage. However, the device's performance and power consumption may vary slightly compared to operation at 3.3V. Refer to the datasheet for specific details on operating the device at 2.5V.
• How do I ensure electromagnetic compatibility (EMC) with the SN65LVDS100D?
  To ensure EMC with the SN65LVDS100D, follow proper PCB layout and design guidelines, such as separating analog and digital grounds, using shielding and filtering, and minimizing signal loop areas. Additionally, ensure that the device is properly decoupled and that the power supply is clean and stable.
