SN65LVDS125ADBTR datasheet by Texas Instruments

SN65LVDS125ADBTR Frequently Asked Questions (FAQs)

• What is the maximum cable length that can be used with the SN65LVDS125ADBTR?
  The maximum cable length depends on the specific application and the signal frequency. As a general rule, the maximum cable length for LVDS signals is around 10-15 meters. However, it's recommended to consult the TI application note 'LVDS Owner's Manual' (SLMA002) for more detailed information on cable length and signal integrity.
• How do I terminate the LVDS outputs of the SN65LVDS125ADBTR?
  The LVDS outputs of the SN65LVDS125ADBTR should be terminated with a 100-ohm differential load to ensure proper signal integrity. This can be achieved using a 100-ohm resistor between the positive and negative outputs of each channel.
• Can I use the SN65LVDS125ADBTR with a 3.3V power supply?
  Yes, the SN65LVDS125ADBTR can operate with a 3.3V power supply. However, the device's output voltage swing will be reduced, which may affect the signal integrity. It's recommended to consult the datasheet and application notes for more information on power supply voltage and output voltage swing.
• How do I handle the thermal dissipation of the SN65LVDS125ADBTR?
  The SN65LVDS125ADBTR has a thermal pad on the bottom of the package that should be connected to a thermal ground plane on the PCB to ensure proper heat dissipation. It's recommended to follow the thermal design guidelines provided in the TI application note 'Thermal Design By Example' (SLMA004).
• Can I use the SN65LVDS125ADBTR in a high-temperature environment?
  The SN65LVDS125ADBTR is rated for operation up to 85°C. However, the device's performance and reliability may be affected at higher temperatures. It's recommended to consult the datasheet and application notes for more information on operating temperature range and thermal design considerations.
