SN75LBC978DLR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the application note SLVAE04, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize EMI.
• How do I handle the thermal dissipation of the device?
  The SN75LBC978DLR has a thermal pad that must be connected to a thermal plane on the PCB to dissipate heat. A thermal via array or a thermal pad connected to a heat sink can be used to improve thermal dissipation. The application note SLVAE04 provides more details on thermal management.
• What is the maximum cable length supported by the device?
  The maximum cable length supported by the SN75LBC978DLR depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 100 meters at a data rate of 1 Gbps. Longer cable lengths may require repeaters or active cables.
• Can I use the device in a non-HDMI application?
  Yes, the SN75LBC978DLR is a general-purpose redriver and can be used in non-HDMI applications that require signal conditioning and amplification. However, the device is optimized for HDMI 2.0 and may require additional components or modifications to work in other applications.
• How do I configure the device for different data rates?
  The SN75LBC978DLR has a programmable equalizer that can be configured for different data rates using the I2C interface. The device also has a built-in link training function that can automatically adjust the equalizer settings for optimal performance. The datasheet provides more details on configuring the device for different data rates.
