USBN9604-28M/NOPB datasheet by Texas Instruments

USBN9604-28M/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from noise sources. Use a common mode filter or ferrite bead to reduce EMI.
• How do I ensure reliable operation over the full temperature range?
  Use a thermal pad or thermal interface material to improve heat dissipation. Ensure good airflow and avoid blocking airflow around the device. Follow the recommended operating conditions and derating guidelines.
• What are the implications of using a lower or higher voltage supply than recommended?
  Operating at a lower voltage may reduce performance and increase power consumption. Operating at a higher voltage may reduce reliability and increase the risk of damage. Always follow the recommended voltage range (3.3V ± 10%) for optimal performance and reliability.
• How do I handle ESD protection for the USBN9604-28M/NOPB?
  Use ESD protection devices such as TVS diodes or ESD arrays on the USB data lines and power supply lines. Follow proper handling and storage procedures to prevent ESD damage.
• What are the considerations for using the USBN9604-28M/NOPB in a high-speed application?
  Use a high-speed capable PCB material, ensure signal integrity by using controlled impedance traces, and follow the recommended layout guidelines. Use a common mode filter or ferrite bead to reduce EMI.
