SN65LVDS2D Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65LVDS2D?
  The maximum cable length supported by the SN65LVDS2D 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 SN65LVDS2D?
  The LVDS outputs of the SN65LVDS2D 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-up sequence for the SN65LVDS2D?
  The power-up sequence for the SN65LVDS2D is critical to ensure proper operation. The recommended power-up sequence is to apply VCC first, followed by VCCIO, and then the input clock signal. This sequence helps prevent latch-up and ensures proper device operation.
• How do I handle the thermal dissipation of the SN65LVDS2D?
  The SN65LVDS2D is a high-speed device that can dissipate significant heat. To ensure reliable operation, it is essential to provide adequate thermal dissipation. This can be achieved by using a heat sink, thermal tape, or a thermal interface material to dissipate heat away from the device.
• What is the maximum data rate supported by the SN65LVDS2D?
  The SN65LVDS2D supports data rates up to 1.92 Gbps. However, the actual data rate may vary depending on the specific application, cable length, and system design.
