USBN9603-28M/NOPB datasheet by Texas Instruments

USBN9603-28M/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 and a shielded cable to reduce EMI.
• How do I ensure reliable data transmission over long cables?
  Use a high-quality, shielded cable with a twisted pair for data transmission. Keep the cable length as short as possible and use repeaters or hubs if necessary. Implement error correction and retransmission mechanisms in your firmware.
• What are the thermal considerations for this device?
  The device has a maximum junction temperature of 150°C. Ensure good airflow around the device and use a heat sink if necessary. Avoid overheating by keeping the device within the recommended operating temperature range.
• How do I handle power management and voltage regulation?
  Use a voltage regulator to ensure a stable 3.3V supply to the device. Implement power-saving modes and suspend/resume functionality to reduce power consumption. Use a power switch or a low-dropout regulator to minimize voltage drops.
• What are the ESD protection and latch-up prevention measures?
  The device has built-in ESD protection. However, it's recommended to add external ESD protection devices and follow proper PCB design guidelines to prevent latch-up. Use a TVS diode or a transient voltage suppressor to protect against voltage spikes.
